There are a lot of boards, and I have seen a few effected. /sp/ /pol/ /news/ /test/ /meme/ and many others = at least a dozen. 

One of those boards is where the spammer began posting his tranny pics. Then the bots came. I did not take a tally of all the boards effected so I don't know how many were, all I know is there were others too.
