+1. I just had to report 2 bots in the same game. One was one of those retarded feedbots, did nothing but walk down midlane autoattacking everything in its path all game long. The other was better-programmed, able to actually buy items, use abilities (sometimes) and move away from enemies that wanted to kill it, but was still terrible and useless (and ironically ended up with less kills and CS than the feedbot, despite starting in a solo lane.
The real irony was that one of the three HUMAN players in the game spent half of it cursing out the other two, having apparently mistaken the (really quite good) Vayne in his lane for being a bot after she "killstole" him the first time. Eventually I had to just mute him and report him for being an asshole.
