i think the 0.2btc buy order could be the bot. if he is out of coins and want to start over again he must buy new coins.
if that is the case then the problem is over as everybody needs to buy coins before they can sell them

it isnt a huge problem as long as bid and ask stay close together. and ofcourse its a market so there will always be traders.
and even if he is planning to buy millions again and then dump then, that would be easy to track as we should see a huge pump.
and a bot isnt stupid...he isnt going to buy high and sell low for long as a bot needs to generate cash.
so i think just forget about the bot from now on and lets just start the real market finally again!
