Obviously because many new members finding this forum late and giving it a try to sell/buy or exchange stuff.
You might be right but maximum trades with newbie account came to scam others. Actually they are not new on this forum they are also old and might be reputed too. But they create new account for trying to scam people. This type of person usually try to post on lending, currency exchange and other trading section.
Ranks means nothing in sales/exchanges if people provide security such as escrow or safe place to meet.
You are right but when creates a post from an old account is serious of the post but when a post created by a new account is not serious. For example OP could not verify either OP has the so called fund or not.
Everyone is equal here, no matter how people around are trying to "flex" with merit, rank, feedback.
Is here anyone who told you are not equal? Or underestimate you?
