if you need to spend extra cash on proxies just to cheat and then receive a ban, IMO it is not worth it. There is a bunch of VPNs that you could use and maybe log them one by one every 20-30 mins so that it would go unnoticed. Hope I helped a little.
there is a rumor right now that a bunch of users who auto-buy and receive a freeze, they are able to unfreeze their accounts. I believe this to be true because of all the stamps right now in shop 58 are just going so fast. =/ They are really getting greedy.
