Its safe, I've bought upwards of 150m (132m in October....so probably more than 150) My account has always been safe, never been hacked by them and no viruses. I think out of all the sites I've used, they are the most reliable.
They got hacked by one of their competitors, but they bought McCafe (however its spelled I don't know lol) They explain it on their homepage.
Trust me you won't be disappointed. One day, they delayed my order a bit, I go mad and told their live chat. They gave me tons of free gold farming (tons since it was a 30m order and I got like 5m) to maintain their positive customer support. Mostly cause my introducer is awesome Candy ftw
I can say from tons of experience that that site is really legit. I haven't had any issues selling to the at all. If you are willing to wait a week, they always come through with payments.
As for buying, I've had tons of accounts recovered. I really can't place blame on the company as I believe that it is the OO recovering it.
I can't really give you a 100% for sure comment.
i got ripped for a account and 60m gold from them. 190.00 total because the original owner recovered. then they tryed to give me a 50.00 account and no gold! so i wouldnt buy accounts from them but buying gold is awesome!
Gold4rs is absolutely horrible with accounts. I sold them my 128 main with 3 99's and 79m+ and they email me randomly saying that "I scammed their account and I need to recover it or my paypal account will be chargeback'd and it would be banned." Seems a little sketchy to me, considering I only bot for my buddy.
