I see a great potential in business of buying and selling bitcointalk accounts , can be done to grow bitcoin, buy account when ranking is still a member and sell them when the full member, I think it's a very safe investment, all things considered.
Also you have to work on that account. Worths nothing if you're spamming or posting just shit. Many peoples buy accounts to get involved in sig campaigns, but many of them are rejected because of bad post quality
I think it's acceptable or not that account in the signature campaign it's not a matter anymore of the seller, he sells only account
or you can create multiple accounts, and waiting a few months to become a full member, and sell
