people are already talking in these comments about a reason to block all of dbzer0 as a result, which I think was exactly the kind of intended response for this to generate.
Probably their goal, yes.
except that it was made by one of the trolls
Yep, I'm aware of the posts, I just wanted to point out two things - that they were deleted so no longer a good reference, and the quotes around anti-AI trolls - which as you say, there absolutely are, and were in that original thread you linked - comes across as dismissing the idea that they exist.
Except there are plenty who are doing the trolling, and the quotes are dismissive of it entirely. Despite you noting that there are in your other comment.
I have no idea, nor do I care to investigate how a mod handles things on a small community.
Here are a few things we do know:
The fact that there are people, such as yourself, getting so riled up over being banned from a community they claim to not have any interest in is also odd. Why would being banned from a community you dont care about even matter?
But let's not pretend there aren't trolls when there clearly are. This also isn't the first time this sort of thing has happened.
Some people are just shitty. Banning and blocking are handy tools for that.
