The only 100% way of not getting scammed, is to not buy accounts. lol.
Accounts without recoveries, mean that the person can get it back whenever they feel like it.
The safest way to buy an account, is from someone who can't remove their recoveries, and do a 14 day trade with a middleman holding the cash.
I mean, I have done several account transactions, and this is the only way I feel is safe, The only way to get a good account safely, is just to wait the 14 days. If anyone disagrees with that, Kindly let me know.
