Like I said, give examples of the kinds of scams that you claim are the result of sold accounts, otherwise you are just making things up
TL;DR: bitcoinblackfriday.info -- brought to you by bought accounts & signature campaigns.
thriftshopping bought the account
GotaPauj on November 02, 2015 and therefore while smith coins, prodigy8, lorylore, jt byte and Prasmatic
were alt accounts of GotaPauj they're no longer alts when the scam happened (or at least there's no proofs of that).
Of course, this is just an example. I remember there was some huge cloud mining ponzi too, with signature campaigns etc., can't think of the name offhand, but huge. Account dealers don't disclose which accounts are being sold, so compiling a full list is difficult.
You're welcome.
