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
Very rightly said mate, people are involved in posting one line comments which doesn't make your account a good one, as they are only trying to increase the posts/activity so that they can become full member accounts soon.
