When the spammer hits the forums, he is able to post over a dozen new threads within 60 seconds. As soon as we spot the posts, we delete them and the spammer's account. When one of us is online, we're usually able to catch and delete the spammer before they've reached the 50 post threshold, so he doesn't succeed in spamming the main forums. On the rare occasion that one of us is NOT online when the spammer hits, yeah, they might be able to post over 50 spam threads that then spill over into the main forums. For the most part though, we're able to catch them before this happens.
