there is no evidence that the whole amount was made by using a bot as the op has said he talked on there a lot and was playing with a bot so more than likely 80%+ of the 0.35BTC was him talking and 20% was the bot right now there is no evidence on how much of it was him and how much was the bot if anything he should only pay back what the bot earned him
Ok, assuming that the bot only made .01 BTC, that means the amount is still wrong, but the principal is the same. Tspacepilot went on TradeFortress' site, and used illegitimate ways to gain Bitcoins. Tradefortress' feedback would still be valid, although he should probably change it to .01BTC if there was evidence.
But really, what is the difference between scamming .01BTC, .02BTC, or .5BTC, either way they would still have the negative feedback from TF and the reason. The arguement here isn't whether or not tspacepilot abused the site and took Bitcoins from Tradefortress, its A) whether its ok to post it on Bitcointalk, a different site, and B) Whether tspacepilot is at fault for abusing the system.
From the hundreds of other cases I've seen, the answer is yes to both. The amount isn't a major factor.
