Wow, heh. Good list! That was actually half the point of this modification, as an indicator of activity. You're the first I've seen it works well.
No, you can't limit the number of sites it adds. Bans are done before a URL is added to the list, so if it already exists then it will continue to count up until the next clearance, at which point it should not appear again. If it does then I've broken the blockwords filter again.
