@experienced The bots are a little slice of evil, I'm not about to defend them.
But maybe the problem isn't really the bots, it's your bandwidth. Most web hosting providers provide way more bandwidth than their clients need. If you're worried about the incremental cost of the bandwidth that a handful of bots are using up, I'm guessing that you don't have enough monthly bandwidth allocation.
