I was kinder to aa than most of the people who replied to him

I really want to hope I can say the same. I sort of took it as my personal mission to respond to every outrageous thing he said, and point out the problems with his politics and his theory of sexuality. As a former member of the online incel community, I thought I was in a better position to empathize with his situation, and could present alternative arguments in a way that he might be more receptive to than standard refutation. But AA never replied directly to me, so I don't know how he took my approach.

Check out the discussion at SlateStarCodex about banning Steve Johnson, a time-wasting fellow who wasn't quite breaking the rules.

SlateStarCodex does not have a karma system, though.On LW, time wasters tend to be downvoted swiftly, so they don't really waste much time anyway. If someone who's broadly considered a "time-waster" is nonetheless upvoted, this tells me that what they're posting is unusually interesting.
