If they can't determine after 15 minutes of watching the player in question is either a fully automated bot or a person using heavy 3rd party tools then they already lost. Any fool can setup a good system to respond to any /tell /say or any of that stupid type of testing. Might as well just tell the GMs to stop wasting their time with those stupid tests. My last playing friend now almost fully automated 24/7 (4 to 5 boxes) can respond to any stupid /tell /say test. What he can't respond to is charming the mob he's attacking and watching his whole box team stare at it for awhile while doing nothing, he can though if you charm and run away beyond a certain point select a new target. His team will stop if you step in the detection range for x period and all log or move to safe spot. It's crazy to watch but the movement of the melee is still pure 100% bot like.
