Quickseller isn't active for about two days and look how quite the forum is.
He had a
LOT of alts.

Catching his alts is like choosing all the green balls from the ball pit. Quickseller talks unlike anyone else. It's too easy to separate his lingo from the rest.
Not really. According to you, BiPolarBob = QS, and IMHO they speak pretty differently. QS isn't dumb; if he had undiscovered alts that he was actively using, he would not use his old "lingo".
Meh, that's a lot more difficult to do than you think. Language and vocabulary are very tricky that way, and tspacepilot's script showed that well. I've noticed this with my own alts. They sound -- like me. I think what people tend to do is throw in capitalization/punctuation nuances, and this makes it "look" a bit different. But if you actually analyze the word combinations they use and their writing style -- that's a lot harder to shake, no matter how conscious you are. Even this is hard to keep up, as you become more focused on the content you are writing and therefore less aware of who you are "supposed to be" (someone else).
Quickseller does have a very particular writing style. The giveaway, though, is that he can't help shilling himself in virtually any argument. He has an obsession with this forum and with being perceived as correct. That makes him sloppy. Like I said, as you become more focused on the content you are writing about, you forget who you are "supposed to be."
I'm watching a handful of accounts that undoubtedly were and likely are still controlled by him. Simply out of curiosity at this point. The end game of coming after Quickseller was to get him removed from DT and neg repped to hell, and that's done at this point.
QS is not BiPolarBob.
I tend to agree, but I haven't really looked into it. Funny to see you here, with all the TradeFortress talk. What do you know about Quickseller, anyway?
