Handle scam accounts

[jbesraa]

Lately there is an attack on the bot where newly created users take offers and do not pay them, requiring the other party to dispute. The scam user then creates fake account that resembles one of the customer support account and contact the offer maker to "solve" the problem, encouraging them to release the funds.

A possible solution would be to block newly created account for X amount of time, unless they are added via referral link.

Additional solution could be to limit new users trade amount until they reach some threshold.
