to be honest, I have used gold4rs for over 30 purchases.
but they are really stupid. apparently, in china the manager can be "out for lunch" 24 hours a day =0 !!!!
and if you buy like a mill from them, check your order when its almost done, then tell the people "yay you got 1m, now you only need to farm 10m more =]"
and they will actually tell the trainers to do it, and the trainers will.... XD
another thing, don't expect much from gold4rs, the chat people have no clue whats going on, i bet if you told them what game you are buying gold for, it would be news to them =p.
basicly from my proven stats, gold for rs has a 0:30 ratio of scamming..erm thats not right...
but i don't doubt they don't scam, they probably aren't trying to they are just really dumb.
(BTW, many people say they got scammed when in reality, for big orders, gold4rs changes the password for safety reasons, THEY EMAIL YOU THE NEW PASSWORD, a reason you should use a random/friends email.)
