Some members sending me pm about trading and other services and other bitcoin talk service.. how can i know this member asking me real or want to scam with me...
Too many the people are promoting their service are having a high chance for to be a fraud, someone is trusting will not for directly making any PM in your inbox. I guess this is just used by the people are having a low trust level, don't trust someone in this cases, without making any PM for you the trusted person are already having a lot of the people are know him in this place.
