They're completely opt-in for server admins and use publicly available information to ban users seen logged into "condos" which are sexually explicit and used to groom children. It's a system called Ro-Cleaner (among others) that allow moderators to blanket ban these people.

The fact is that Discord and Roblox aren't doing anything to prevent this activity despite being responsible for facilitating it (condos are published on private Discord servers). When people report these servers or the condos they refuse to do anything meaningful.

I haven't actually seen any evidence of doxxing/harassment. The system does not collect information other than usernames and the activities of those users in Roblox, both of which are publicly available. I would be interested in hearing whatever information you may have on this.

So is discord providing a better alternative to monitor ban the creepy predators then, even if these bots are flawed are they not providing necessary security
