again, it won't matter what you do. the original owner can ALWAYS recover an account, even a year or more after it had been sold. you have the owner's IP, you know the exact information of when/where it was made. the one who makes the account will know all there is to know and be favorable when jagex decide who the account belongs to if you are ever to try to reclaim an account.
donating/whatever to the site might give you a little more credibility, but at least i can say that i don't care about the color of someone's badge. if you sell accounts then you could sell 4b worth of accounts over time then decide to scam quit and recover them all at once.
