I was a volunteer moderator on a pretty popular game community for about 6 years, where the active userbase sometimes exceeded 10,000 online at any one time. We had plenty of 8ch garbage people, coordinated spamming from nazi IRC channels, Trump assholes just being Trump assholes, and sketchy CP pervs skulking around.
I am as annoyed by moderation as most people are, but people aren't going to moderate their own chatrooms and communities reliably, if at all.
If you're thinking of a scripted or AI moderation system, good luck, though who knows. Maybe AI moderators might work in the near future, though they'd be pretty fun targets to troll. Word bans, blacklists and offensive syntax filters are a nightmare to maintain, that's the way channels have been moderated for the past 30 years.
The sad truth is that safe places require human moderators who care about the community to spend time protecting it. It's a job nobody wants to do and burnout is a bitch. If there were a few trustworthy people who have a lot of history with perchance and the community who could be online, having it set up so that users could just ping them reports of abuse/scams/CP and they would have the power to intervene on anyone's thing that was opened to the public.
That's the only way. Spending time trying to code a way around this is going to suck your brains out.
I noticed you outright block vpns in the chatrooms. That certainly helps. Systems I've seen that rely on voting can certainly be abused too, of course. I am happy to hear that there are already volunteer mods on here, and yes I was speaking from experience in the community management world, not as an author.
Thank you for your great project. I didn't mean to come off as overly pessimistic. Some scars... do not heal...
