Wilder doesn't necessarily equal more anonymous. I spend a lot of time on little forums where I might not know someone's irl name but I know who they are.
One of the great losses that came with the end of the forum era was all these little communities with distinct cultures and regulars that you got to know.
I kind of found a similar vibe in some discord servers, but they're much more difficult to join as a new user than a forum because old information isn't easily searchable and discussions aren't as longform as old forum posts were.
