There are many newbies who create multiple accounts to scam members who are unaware of the use of escrow and so I would request if there could be some kind of restriction in that section for newbies and junior members, it would reduce the scams. It's just a request.
It wouldn't reduce them, it would just delay them. You can have a Jnr account in a minimum of 16 days so people would just wait out any restrictions you put in place, and as has already been said lots of genuine people sign up to transact on this forum so it's unfair to restrict them on the basis they may or may not scam or be scammed.
