This one math forum I mentioned in another thread had spam problems. This other one I mentioned had graphic problems. However, as I said, I don't know the cause. Could it be the owners of the forums?
I can't say that there was much I disliked about vBulletin when I used it until they moved to vBulletin 4 and I found that the way they changed things I was not keen on and that was around the time when they released Xenforo so I ended up moving over to there.
