Pretty close within eachother.
BiPolarBob could have made the account as an alt of even someone else (He seemed to know quite a bit about bitcoin, and obviously had a lot of bitcoin so he was probably on the forums even before June 15th).
And check out the first posts of BiPolarBob
https://bitcointalksearch.org/user/bipolarbob-343899They are instantly giveaways, so the account was created just to make giveaways/build trust.
Quickseller's first posts were selling accounts
https://bitcointalksearch.org/user/quickseller-358020Why the hell would a "newbie" instantly be able to sell bitcointalk forum accounts.
Hell, why would he know that accounts are even be able to sold on here? Wouldn't he just be asking basic questions, not diving headfirst into our (full of scams) marketplace.
It could be a huge elaborate scheme, and the evidence makes it pretty damn believable.
