While I agree that it is childish to use it as a tactic, as long as real life emergencies/distractions exist, I don't know what could be done to prevent it. I'm not into 'shame-policing' the AH community but I am surprised how shameless a response that was. Granted, I don't really tank in AH and I do like to see poor behavior first-hand before I write off someone as pitiful. But if it came to such, that's all I could really do. Let them be pitiful and go my merry way having fun in other ways in the MA.
