Sometimes people can be rude. I seldom go to merlin_finders now because there are some constantly asker(?) post for record again and again, and it seemed that they didn't go through tags at first. It really ruins my mood.
I can understand why they feel they need to emphasize they don't slash, since there are not many gen fic in Merlin. If it's in their own space, FF.net or not I don't care, but if it's in the request it's insolent.
