Spam has completely vanished, got 0 in a month. Quality and length of comments has gone way up. Turns out that the extra click required and registration weeds out a lot of the problem comments. I also find that giving people space, proper preview and excellent followup makes a world of difference (Discourse has reply by email, notifications and so on) Originally I was considering adding a traditional, add anon comment box, but I am not really that motivated to do so.
