Then he have about 140 green trust. So it's really impossible that it is a bought account .
I really don't like the fact OP ignored the sign requests and then went offline.
Well, i could be agree with you but if someone bught an account like this (140 green) probably has paid more and more than 0.2BTC : so if buyer ask for loan of 0.2 and sign message too , probably is intention is not to scam. Prabably a scam alert could be around 0.6-0.7 that is near the value of the account. In that case he hasn't sign any message, so this probe that account is probably hacked.
