Case Study Filtering $%&#^#$ from the Edge of Space
When Microsoft launched the Pegasus II unmanned high-altitude balloon to demonstrate its Azure IoT platform, they streamed real-time video from the craft and invited the public to send SMS messages back. These texts ultimately became a permanent part of the flight recording.
Microsoft chose WebPurify to moderate the live SMS during the balloon’s journey. We ensured that not one single offensive message slipped through our profanity filters.

What is a Profanity Filter?
Profanity filters were created to block users from posting offensive text such as curse words or racist terms. They filter out a predetermined list of words, but typically also allow the customer to create their own custom “blocklist” of additional words or phrases they want to prevent that are more specific to their brand’s concerns. An effective profanity filter service is not simply a list of offensive words, but an advanced algorithm designed to catch the various and creative ways users attempt to obfuscate those words such as replacing letters with numbers (leet speak) or using repeated characters. When selecting a profanity service, remember to ensure that it covers the various languages that your users speak.
The results of the profanity filter can be used in various ways, from simply preventing the post/comment from populating on the customer’s site, escalating it to their internal team for further review, or replacing the offensive language with asterisks or other symbols. Sometimes, profanity filters will also allow customers to create their own “allowlist” for words or phrases they wish to permit, as they may want to modify the strictness of the filter.
Profanity filters are typically easy-to-integrate APIs that run in the background as your users post to your site.
