There is an answer here (screenshot) which does not attempt answer a question and instead posts a joke in response to a whimsical bounty message. Several people flagged it as NAA and it quickly accumulated many Recommend Deletion flags in review, but the flags were declined. Is there a different standard for what counts as an answer on this site? Are answers which contain nothing but a funny image acceptable?
The bounty message, which was unrelated to the topic of the question, mentioned that it would be awarded to anyone who posts a random, funny answer or says that the OP is an awesome person. A funny answer was indeed posted (which did not answer the question), and it was given the bounty.
The answer even states:
Here is a completely unrelated answer with a funny picture!
As the answer was visible for at least 60 days and has at least +3 score, the author won't lose any reputation if it gets deleted, including the bounty reputation.
