I noticed that this question got bumped to the front page recently. By clicking the
?lastactivity link I was taken to just the top of the question and saw no edits or answers since November, which probably means that whatever bumped it was deleted. The user that caused the bump has no rep or actions so I'm guessing it was a "not a real answer" deletion.
This seems a bit lame to me. At the end of the day, a question got bumped onto the front page for no real reason. It has no reason to take up space there; it's already been sufficiently answered and the only cause of the bump was an answer that (most likely) wasn't a real answer.
I think that if a question gets bumped because of a new answer, and that answer is deleted because it's not a real answer (or is spam or whatever), the question should get unbumped.
