Hey
,
As many pointed out, newer accounts are viewed more risky due to the fact that scammers tend to create fresh accounts frequently. However, that attitude will quickly go away in time.
Stay active, always use a mediator, and remember that the 2/3 rule is completely made up and you do not need to follow it. Using a mediator is by far the safest and most reliable option for trading.
Additionally, though it is not required, to add a little bit more credibility to your account, I would invest some time into it by getting a signature/avatar as well as providing some background info.
These are small things; however, they might indicate that you are interested in staying here for the long term. Report all off-topic posts as spam and do not reply to them yourself.
Best of luck out there!
