Building trust in a community-powered marketplace: Depop’s trust & safety playbook

When people talk about marketplace Trust & Safety, they tend to reach for the obvious threats of fraud, counterfeits, and payment scams. And those risks are very real. But on Depop, where listings aren’t just inventory and transactions aren’t just transactions, the harder work often sits inside the relationships that make a “people-powered” marketplace function.

As Sophie Walsh, Depop’s Global Director of Trust & Safety, recently explained in conversation with Ailis Daly, Head of Trust & Safety, EMEA, at WebPurify, an IntouchCX company, “Our community creates the experience that everybody then has.”

That’s a deceptively simple line with big operational consequences. On Depop, sellers are usually buyers too, and listings can be “expressions of our community’s identity… the output of their personal creativity and even linked to their income.”

In other words, enforcement alone can’t scale trust here. Depop’s approach is a useful case study in what it looks like to build safety with a community – through education and clearer expectations, plus the kind of consistency that makes decisions feel fair – without turning the platform into a “computer says no” machine.

Trust & Safety when culture, creativity, and commerce collide

Depop is a marketplace where commerce is inseparable from culture. And when buying and selling are tightly fused with identity, moderation decisions land differently.

Walsh explained why: because Depop is peer-to-peer, Trust & Safety isn’t something the platform simply applies or enforces onto users. It’s built with the community, and that makes decisions more nuanced. The stakes don’t just look like a removed listing; they can look like a user feeling personally judged or financially harmed.

That nuance is amplified by how content moves. On Depop, content doesn’t just exist in isolation; it’s discovered, shared, interpreted, and responded to by others on and off the platform. So the Trust & Safety profile of a single listing can change depending on how it’s engaged with, and what it signals to other users.

In community-driven commerce like this, trust is a lived experience shaped by clarity, consistency, and how people feel they’re treated when something goes wrong.

The guiding principle: maximize expression, prevent real-world harm

If the content is personal, the policy philosophy has to be coherent. “At Depop, we focus more on prioritizing free expression when it doesn’t cause real world harm,” Walsh says. “That is really our starting point.”

But that doesn’t mean “anything goes.” “Rules are really important as a minimum standard so that everybody understands what is expected of them,” Walsh explains. “But we also do take into account context often when we’re moderating.”

This is the first major theme: in marketplaces that blur into social platforms, Trust & Safety lives in interpretation as much as in rule-checking. You can’t build legitimacy purely on enforcement volume. You build it by demonstrating a consistent theory of harm and then applying it in ways your users can understand.

The work that consumes time: prevention, education, and expectation-setting

One of the most useful reframes in Depop’s approach is that much of Trust & Safety is about preventing issues before they happen.

Prevention, in Depop’s model, is heavily education-led. Walsh describes focusing on helping well-intentioned users understand expectations so issues don’t arise in the first place. And when users make a genuine mistake, Depop aims to give them an opportunity to understand why what they did wasn’t in line with the rules and how to avoid making that same mistake again.

That stance rests on a human assumption that many issues arise from users wanting to do the right thing but simply lacking clarity.

Walsh also points to the concrete education infrastructure Depop has built across app and web, through resources like the Help Center, community guidelines, and safety tips.

Of course, proactive work is easy to advocate for and hard to protect in practice. “It definitely requires very firm intention to carve out the time to move from reactive to proactive,” Walsh explains. “That culture of urgency can really snowball, and it can feel relentless at times.”

The point isn’t that every platform can mirror Depop’s exact approach. It’s that prevention isn’t just a nice-to-have, but rather a long-term strategy that reduces future enforcement load and strengthens user trust, especially in community-powered contexts.

A case study in cultural change: Washington Redskins merchandise and “living frameworks”

The clearest illustration of “Trust & Safety as relationship management” comes from Walsh’s example about users selling merchandise for the NFL team the Washington Redskins (since renamed the Washington Commanders).

Depop reviewed its position in a complex cultural context. Vintage sportswear matters on the platform, but the team aligned with broader industry consensus and the organization’s official name change, which reflected growing recognition that the former name and branding were offensive. As a result, Depop classified it as prohibited content.

The enforcement decision, however, wasn’t the full story. Walsh noted that many sellers were genuinely confused or frustrated. For some, it was simply a retro item they’d owned for years with no intent to cause harm. And in several cases, users weren’t yet aware of the broader cultural shift around the name.

This is where Depop’s model becomes particularly instructive for marketplaces operating across geographies, age groups, and subcultures. Harm prevention has to coexist with context and education, because user intent and knowledge won’t be uniform.

“It’s really important that Trust & Safety responds as cultural norms evolve and that we support a global community to move with those changes,” Walsh says. “That means balancing harm prevention with education, context, and empathy. 

“This case really underscored for us that policies aren’t static rule books – and never should be – but living frameworks that have to adapt alongside changing societal expectations and norms.”

For Trust & Safety teams, this case study captures a familiar dilemma: if you treat policy as immutable, you fail to respond to real-world harm; if you treat policy as flexible without clear explanation, you lose legitimacy. Depop’s answer is to combine adaptive frameworks with clearer communication and educational scaffolding so change doesn’t feel arbitrary.

Secondhand goes mainstream: designing protections for mixed experience levels

Depop’s Trust & Safety model is shaped by the fact that secondhand is no longer niche behavior. Resale has become far more mainstream, and Depop has had to adapt to a wider range of users.

Walsh explains that when your user base broadens, you can’t just rely on an assumed level of platform literacy or resale knowledge. That pushes education and clarity even higher up the priority list, not only in policies and guidelines but in how processes and outcomes are explained, and what good participation looks like. “The clarity piece becomes even more important, not just in our guidelines and policies but in how we explain processes and outcomes and what good participation looks like,” Walsh says.

It also raises the importance of feedback loops. Walsh emphasized the need to sense-check whether protections and proactive guidance are actually landing with that broader audience.

And then there’s fairness. In peer-to-peer commerce, users arrive with different levels of confidence and perceived power. Walsh’s lens is fairness and accessibility, ensuring protections and processes work just as well for somebody selling their first item as they do for a highly experienced seller. 

“We must always be thinking carefully about fairness and accessibility,” Walsh says. “We want the protections and the processes to work just as well for somebody selling their first item as they do for a highly experienced seller, for example. So really we’re talking about clearer pathways for support, dispute resolution, and review being very, very important for all, regardless of experience or confidence.

This is an important reminder for any marketplace scaling into mainstream adoption: your Trust & Safety system has to be legible to novices and credible to power users or both groups will find reasons to distrust it.

Why “rules” are the easy part: trust is built in explanation and consistency

A common failure mode in marketplaces is binary enforcement paired with opaque decision-making. Depop’s approach is essentially a playbook for avoiding that.

The risk of getting the “honest mistake vs bad behaviour” distinction wrong is significant. If people feel they’re being penalized for honest mistakes, it creates a loss of trust. On the other side, if bad behavior isn’t addressed, it can undermine confidence in the marketplace and discourage participation.

So what holds the system together? Walsh points to proportionate responses – things like review mechanisms, clear communication, consistent application, and escalation paths that match severity – so users feel the system is fair and grounded in informed judgment, not fast, subjective assumptions.

This captures what many platforms aspire to, but struggle to operationalize: fairness isn’t just a feeling. It’s an output of well-designed processes, consistent decision frameworks, and communication that helps users understand the “why,” not just the “no.”

Content, bodies, identity: reducing subjectivity with decision frameworks

Depop’s context-heavy environment makes one category particularly sensitive: content moderation around bodies, aesthetics, and identity.

“It’s really important that we have clear internal policies for our agents to follow to help them make an objective decision every time, rather than basing moderation decisions on subjective judgment,” Walsh says.

If decisions are left to personal taste, inconsistency and bias follow quickly. So Depop focuses on creating conditions where agents don’t have to make subjective calls. “We focus on having really well-defined policy definitions plus guidance for agents who also use decision trees and visual guides to help them make really consistent decisions and avoid bias in this area.”

The aim is to prevent agents from having to make subjective judgment calls by designing policies that maximize expression, account for cultural differences, and draw firmer lines only where content is harmful. Then it’s about ensuring those policies hold up in practice through QA, calibration, and training.

For platforms wrestling with high-volume edge cases, this is a practical reminder that “human judgment” doesn’t have to mean “anything goes.” Humans can be guided by frameworks that reduce variability while still allowing for nuance.

Mission matters: sustainability as a trust flywheel

It’s easy to treat mission statements as marketing copy. Depop’s mission, however, directly shapes what Trust & Safety has to deliver.

Walsh describes Depop’s mission as “make fashion circular,” and explains that to enable that, the experience has to be functional and “magnetic” – intuitive and reliable, but also full of personality and worth returning to.

Because the circular model depends on long-term participation, Trust & Safety isn’t just about stopping harm in the moment. It’s also about supporting safe participation over time through clear guidance, fair processes, and support that works whether someone is a first-time buyer or a seasoned seller.

This flows into user expectations. Because Depop is built around community and human connection, many users want more than efficient transactions. 

“Our users are engaging with people whose style and values and stories they truly relate to,” Walsh says. “And we really pride ourselves on being a people-powered platform and not just a transactional one.”

That expectation affects enforcement tone. Walsh says Depop has taken signals from users on board, developing communications that feel more personal and tailored to different user bases.

If your platform’s value proposition relies on community, your enforcement model has to feel human, not because it’s soft, but because it’s aligned with why people show up in the first place.

Humans + AI: AI as “bridge,” not judge

If all of this sounds highly human – relationships, expectations, empathy, and the feel of fairness – that’s because it is. But at Depop’s scale, “human-centered” doesn’t mean “human-only.” The job is to preserve nuance without drowning in volume.

That’s where AI enters the picture. Depop’s approach to AI in Trust & Safety is practical: it’s most valuable when it helps teams see patterns that are difficult for humans to spot alone – things like emerging trends, behavioral shifts, and early warning signals.

“We think about AI very much as a bridge and not a barrier,” Walsh says. “So helping to translate information, reduce that cognitive load and give people better inputs to make those fair decisions. And it’s used to support human decision making rather than replacing it.”

Automated systems alone can’t reflect community values, she says, and many decisions require nuance and human insight.

And the governance principle remains consistent: humans need to stay in the loop, especially when decisions are judgment-based.

Trust is a shared system

Depop’s Trust & Safety approach is a strong example of what it takes to build safety in a community-powered marketplace:

• Start from a clear harm philosophy
• Treat policies as adaptive frameworks, not static rulebooks
• Invest in prevention through education and expectation-setting
• Build fairness through proportionate responses, review mechanisms, and clear communication
• Use AI to surface signals and patterns, while keeping humans in the loop for judgment and legitimacy

If your marketplace is becoming more social or your community is becoming more mainstream, those lessons are the difference between a platform that merely enforces rules and a platform that earns trust.
