On a recent question, there was an accepted answer that the community seemed to disagree with. I went back to the answer later to see what had happened, and discovered that the accepted answer was completely removed. The last score I saw on the answer was -4.
I think I've seen other accepted answers with the score well into the negative territory. But it seems weird that the accepted answer did vanish. Do significantly downvoted accepted answers automatically remove themselves?
After some research, I found http://meta.stackexchange.com/a/79582/215013, but it seems that only a flagging or a moderator can remove an accepted answer. But the accepted answer did answer the question, even if it was unpopular with the community.
