players accusing you of being a bot

[tekmo7]

i only get this claim when i am playing heads-up plomaha or limit...usually comments like "bots don't win" or "got nothing to say bot?!!!" when i don't respond to chat abuse...how do players come to this conclusion? will i ever have anything to worry about considering what happened in the gatorade scandal? has anyone else had this experience? your views are appreciated...thanks.
