I think it's something where Kbin sends an insane amount of duplicate AP messages or something like that.

Every time my instance falls behind with them, there's usually some community ban in LW's modlog soon after about a kbin user sending suspicious traffic. My understanding is that's unintentional on that user's part.

I thought there was a post breaking down the problem but I can't seem to find it.

Edit: It was in admin chat, not a post (or if there was a post, I still can't find it).

Kbin (the software) is like the bad neighbor in the fedihood.
