The vast majority of these reasons are not scam related.
ORLY? How do you figure that?
I believe that a very low minority of sold accounts are used to attempt to scam, and of those, a very small percentage of accounts are ever successful at scamming.
Ohhhh, you *believe* there's only a small minority and, even then, you're going to claim that *only* a small percentage of that tiny minority successfully manage to scam anyone.
SMH. Where to even begin with that fallacious reasoning?
You spent so many words explaining why people would sell an account that it might confuse people into mistakenly thinking that your reasonable assertions explaining the seller's side of the process, also holds as reasonable for the buyer's side. It doesn't.
1. The very act of buying an account with good standing and a high member ranking is to defraud the natural process of social selection all users have to go through in establishing their posting history and community standing.
2. Anybody who promotes anything through a high-standing account they have purchased is being dishonest and deceptive, unless they are willing to clearly state in their signature or avatar text that it is a bought account, which would make the purpose of purchasing an account pointless, right?
3. You state that a buyer would have a greater incentive to try to scam if they know they will receive negative trust for it being a bought account, that is laughable. You are essentially saying, "Don't piss these dodgy bastards off, otherwise they'll *really* work harder to defraud people.
4. You then state that owners of accounts who are desperate for money would try and scam if they couldn't offload their account to someone else, which is basically the same thing as saying, "Desperate people should be allowed to sell their ID so that scammers will defraud forum users instead of them having to".
5. As for claiming it would do more harm than good to nuke sold accounts, I disagree, the trade in this dodgy practice would soon become pointless, thereby drastically curbing the number of fake high-ranking account users if was clear that sold accounts were being torched once discovered to not be the original owner.
Give me three valid reasons why somebody would want to buy a high-ranking account which wouldn't count as deception?
I'll save you the effort, don't bother, you can't.
