Since you can easily recover your Combat Arms account back in less than a minute right after trading it, there'll be a new rule for those who wish to sell/trade their accounts.
You will have to provide the email associated with the account before the trade and that email has to be the one that was on the account before you trade it. Meaning that if a change email request was found within the past 24 hours, you will be considered a scammer.
So make sure to read this.
Good luck trading, and always remember to use a Middleman for a safer trade.
