Readercon's failure to abide by its own policy on harrassment
Well, there is a follow-up post regarding what the board decided to do about it. Unlike previous incidents that went according to their policy, this guy is banned for 2 years and then allowed back if he doesn't harass anyone during that time. Apparently he felt really sorry so they're breaking their policy for him (no, seriously).
If you're reading this community, you know why that's a problem (and if you want some confirmation, the comments on that last link will provide it in abundance - at least that gives me hope for the future of fandom).
ETA: A link roundup, so you can also see the many responses to the response.
