Dear daddy, this thread is my therapy so shut your trap before I tell mommy what you did to me.
To answer my own question as to why Quickseller would need to rank up an account to Legendary: He's likely trying to start fresh with another account that doesn't have red trust so voluminous that it could paint a street full of houses--but as with his other alts, he basically got caught by his own writing style.
The thing is - and I think I posted something to that effect in nutildah's alt-busting thread - that in the ~5 years since the escrow fiasco he (Quicksy) would likely have been able to do a fresh start in an honest way.
But he seems to be uninterested in or incapable of admitting that sleazy sockpuppeting is a problem, and he's betting that most signature drones in this thread and elsewhere on the forum don't really have the attention span to notice his scheming. And winning that bet bigly.
All we can do is hope that he spent those 5 years just to get to the point of being able to earn $100 per week (or whatever it is) in a signature campaign and not to run a proper long con.
