Worst forum I was ever on was a vegan forum. Now defunct. Biggest bunch of nasties and they all wanted to agree with each other. Lots of virtue signaling.
I watch a live stream sometimes, Tiny Kittens. Their live stream has 3 rules: No all caps, no more than 3 emojis and no roll calls. So this, yes troll, starts posting in all caps, moderator kindly writes something, then it's a string of emojis, again moderator intervenes, then started asking roll call questions. Can't even leave the kitties alone. I hope they banned the person. I clicked out because they were getting on my nerves. Have not noted a return of this behavior.
