I agree that the teleporting glitches that the bots use is a terrible exploit and somehow is still around even though it was known about in the Beta... This, however, doesn't mean that even if they remove the glitches there still won't be bots. People had bot programs that would run you around the map (including obstruction avoidance) and automatically gather by sending legitimate commands through to the client through the keyboard and mouse drivers as if someone was actually playing. It just proved more expedient to use the glitches that were found.
