A bit harsh. The s*** word is hardly a profanity these days and it wasn't directed at anyone or used in a nasty way. Anyway how many strikes before you're out.
True, it might have slid by in the post itself, but certainly not in the title.
3 and you're out, however, cards are reviewed occasionally and can be removed at the mods/admins discretion. I wouldn't worry about it, just be sure not to do it again.
