Astroturfing.
Offensive mailicious spam. Discsrimination marginalization of Nameless Anon. Vatican spammers.

I kind of had hope for this site to be safe. Or you having non-js protection system in place. Accounts? Weeb captchas? Voting system? AFAIK ip ban isn't a way. Premoderation ala 1chan? AI word/spam/link filter?

If shit repeats/be posted - I'll leave to mastodonostr embracing brave new world of content filters, reputation, clean n tidy feed
