When someone asks a question on Gaming, they may tag it as spoilers to warn other people off. However, what if the answer to a question contains spoilers? For example, This Question of my own (this may not be the best example, but it was easy to find). Upon receiving the answer, I retagged the question, but there still exists a gap of time in between the answer being posted, and the op retagging the question. And this is, of course, assuming that the op is a regular user who returns to retag it.
Yes, I'm aware that the answerer blanked out his spoilers, but even still, I think the question should have the tag if the page contains any spoilers at all.
So, I was thinking, what if users were given the option to add the spoilers tag to any question they answer? I was thinking of a simple checkbox, that asks something like, "Does this post contain spoilers?", or "Will this post create spoilers on the page?". Obviously, there would have to be a rep requirement for this ability.
