While I'm deeply concerned about the possibility that AA has been engaging in vote-gaming which does seem to be a bannable offense, it isn't clear to me that, as reprehensible as that comment is, that it is enough reason by itself for banning, especially because some of his comments (especially those on cryonics) have been clearly highly productive. I do agree that much of the content of that comment is pretty disgusting and unproductive, and at this point his focus on incel is borderline spamming with minimal connection to the point of LW. Maybe it would be more productive to just tell him that he can't talk about incel as a topic here?
