What's to be done? They ban people where bans are deserved. Almost every comment that's off-topic has been flagkilled. The system seems to be working pretty well. The comments are unpleasant for the ~8 or so minutes they're active, but they go away swiftly. It's hard to imagine a solution other than pg's "all comments start dead and need a vouch to come alive" idea from several years ago. Reddit deals with this situation by locking threads entirely, which many people wish wasn't a feature. Do you have any other suggestions?
