Read it somewhere ,
"when you create too many accounts from a single IP , the IP is considered as a TOR Node or a public proxy and it is banned and thus you can not make anymore accounts though you can still use the one's already made and they won't be banned"
So it's better you use some proxy to make the accounts , account trading is really so much atm , i see Digital Goods Section full oF BCT account , it should stop though sadly i don't think it's possible
