Nah, they'll just move his post to the Garbage Bin, ending it, and maybe PM him telling him to check the rules before posting.
There's no rule against making a stupid-ass mistake, but it ain't like he's one of the shmucks who come on here with their first post as, "How to I join these RAR parts I got from a bitorrent site?" ;)
At least the rest of us get to have one hell of a laugh about it/him.
