This members where as well legit till they scammed :
Master-p
escrow.ms
Muhamed zakir (or something)
and the list can be longer!
So it's totaly fair to ask him to sign his wallet
master-p was not the scammer. The account was sold and the new owner did that
escrow.ms also never scammed anyone. He was caught and arrested outside the bitcointalk for Bank card fraud
And who told you Muhammed Zakir is a scammer ? Show me proof
