They are apperently tracking Maphack and bots based on your average time spent in a game, which is of course wildly innacurate and discriminatory. Theoretically you could be banned if you were monitored doing legit pindle runs for 2 hours straight because they would assume no non-botter/maphacker would do that, hell even speed cows could get you in trouble. As far as MH being detectable I dont think so.
