This is one of Quickseller's alt accounts?  If that's true, I was definitely not aware of the fact.  Do you have a link or something as evidence?  I also don't see any feedback from Vod on PrimeNumber7's account, though I do see some from nullius in which he states that he doesn't think the account is QS's.

Somehow, it doesn't seem like QS would create a thread like this if it were indeed one of his alts (but I could be wrong).  Also, the escrow scam perpetrated by QS has been owned up to and apologized for, to the best of my recollection, and QS has also made peace with Vod.  I get that people carry long-term grudges against scammers, but QS hasn't repeated his shenanigans and at the very least hasn't been a negative presence on the forum since he got busted for the escrow stuff.  I couldn't stand him for the longest time, but last year when Theymos encouraged the community to bury the hatchets, I became willing to look past QS's previous misdeeds (though I still don't trust him completely and likely never will).

I'd still be very interested to know how these two accounts were linked.
