I didn't trust TF's word, I read through this thread and found that it was admitted that the OP cheated TF out of an unknown amount of Bitcoin. The amount is/was disputed however I think it is pretty clear that that the OP scammed. MZ quoted the relevant posts here although there are more posts that point to his guilt.

I don't trust TF and don't like putting pressure on people to help/repay him however a scammer is a scammer.
