is there a federated platform similar to 4chan ie. topic boards with ephemeral linear message threads? i dunno how else to describe it but I like the 4chan format, it’s just got the worst people in the world on there (which I figure could be mitigated by the federated server type thing)
Anyplace that allows, or in the case of 4chan, encourages purely Anon posting is going to be a cesspit. When there’s no accountability, no ID of any sort (even a screen name) to tie actions against then there’s no reputation to protect. It might be pleasant at first, but you can bet it won’t stay that way for long.
you can make anonymous accounts for free on fedi, the best way to deal with it in both cases is to block tor and IP ban. either way i think freeze peach folks will avoid any platform with “woke” rules
If it has the BlueSky moderation tools I think that could go a long ways to keeping it a pleasant place. Quality moderators can help steer the culture of the boards as well.
