This should really be stopped or done only within trusted members network. It's very much ok that way than selling senior member account or full member account to some newbies
taking away the registration date , activity count and post count would be the best way to solve this or at least make it invisible so every member appears equal
no trusted
no senior
no hero etc
take away the incentive to buy trusted accounts to use in scams ......
This would be counterproductive and have the opposite effect. Scams would go up considerably if we were all 'equal'. Age of account, activity and trust etc are all helpful when dealing or trusting a user but that doesn't mean you should blindly trust everyone who has a certain amount of those things but they are all valuable informations to help you make your mind up about an account. Should long-time and trusted members like tomatocage and vod etc be the same as some random newb? No.
ALL DEALS SHOULD BE DONE WITH ESCROW
the amount of time anyone has spent making posts has no correlation to how trustworthy they might be
Dank is probably the greatest example of a complete degenerate with the status of "legendary" just because he posts a lot of crap....
How would newcomers tell how trustworthy an escrow was? How long someone has been around is very relevant especially when you factor all the other different parameters you propose to get rid of. Age or number of posts etc doesn't equal trust by itself but when you factor in other things like the trust system it gives you a pretty good idea of who you can and cannot trust. If everyone was on a level playing field from newcomers to long-time trusted Legendary members it would be a nightmare.
