In our game users can set usernames as raw-text, and we need some way of filtering usernames. I found a https://www.webpurify.com/documentation/methods/replace/ to be able to do what we need. Looks like we could query their API from gamesparks servers when needed. But to use their API's we need to white list a domain or IP address. Is there a specific domain that covers all gamespark servers?
Or is there a better way to do profanity filtration? :)
