pardon me but this looks like a longer version of ban list with reasons?
What if spammers just create really massive one-off accounts? A lot of computing power would be wasted on comparing billion rows of user ids.
Another issue in MSC2313 is the {"reason": "undesirable behaviour"} is too short. What if a legitimate user is wrongfully banned? What's the appeal process? What if the un-ban didn't propagate into proper servers?
