As shorena said, it doesn't make economic sense to scam/spam with a purchased account because that would mean loosing the money you just spent on buying said account. Doing this would more or less be throwing money away.
Quickseller often invokes this sort of rationale

Alright, lets get the fallacies out. This is a personal attack, which does nothing to devalue the arguement at hand.
The argument "pay X for account, must scam >=X to ROI => account trades make scams less likely to be profitable" was introduced by Salty IIRC.
-people are irrational-
Yes, like these ratings. "account was traded => new owner
will scam/spam" is not rational. Neither is "trades account && traded accounts result in scams => account trader is scammer". We can agree that a new owner
may scam or spam and try to find evidence of the likelyhood.

Another trick quickseller employs is for s/he and one of their alts to engage in conversation backing each-others assertions about a point...

Which is a useless tactic if you argue with arguments and not against or for the person.
