A common theme among the people who are voicing their opinion against the sale of forum accounts is that the sale of accounts leads to scams. I would however question that conclusion and ask how many scams (both as a percentage of account sales and as a percentage of forum scams) are from sold accounts and how many of those were made possible (or at least aided) by the fact that it was a sold account. I would believe for that number to actually be quite low and in the grand scheme of things, allowing the sale of accounts probably actually decreases overall scamming activity because it gives people who are desperate for money one additional way to get money that does not involve stealing from others.
Of course you are going to defend it but you were selling DT accounts too as far as I know, would you say those accounts can't be used to scam? How do you know? A lot of proven scammers just buy another account to keep scamming, is not like people who are desperate for money would buy accounts to scam.
