I will freely and straight up admit that we dropped the ball hard on watson and that was unacceptable. He should never have been given such free reign to post consistently racist and fascist apologia on this website.
The main thing with watson was that it was always just below the line. Everyone knew what he actually meant, but he was very clever about not going out and posting what he truly thought, i.e. "non-white people are subhuman". And, although we do try very hard to keep politics and moderation distinct and keep it to the the way posters interact with other posters, I suspect he took advantage of the committed small-l liberalism of the most active contingent of the mod team wrt the N+P section, meaning that we're reticent to ban people because of their politics unless they go full 1488 or Stalinist. Nonetheless, we (I) should really have put the hammer down earlier because it's not like we (I) didn't know exactly what he was actually saying, and I don't blame Jono one bit for finding both it and our moderation intolerable in that regard. Eventually we did just go and get rid; mindless legalism with regards to "can we shoehorn individual posts into infraction categories" shouldn't have been an impediment to "yeah look this is just not acceptable".
I know it's an issue that's cropped up several times with various posters about the difficulty of dealing with consistently bad, aggressive and disruptive/trollish posters within the bounds of the infraction system. Blocky, Miyagi etc etc fall into this category too. I don't know what the answer is short of scrapping the infraction system full stop, but I'm open to suggestions.
