This answer about aggressively handling people smoking in public has a negative score. I don't know what the score was when the bounty was first offered, but as of right now, the users seem to agree that it is a problematic answer (myself included). Yet the Community has offered a 500 rep bounty for it being "exemplary."
I am ignorant of how the Community offers bounty, so could someone explain what exactly happened here? Also why it happened?
