Besides whom do you think would accept to sell his account at a very cheap price whereby if they succeeded working into signature they could earn higher than that so anyone giving attention to that thread could likely get scammed by them.
They did sell that way in the past but that was when account sales wasn't a heinous crime and signature campaigns weren't that much a thing. Anyone quoting those prices now for account sales is not likely to commit to the agreement. Newbies should keep off threads like that.
You comparing now that signature campaign is now much to then and I know too well that no one will accept to push out their account with such a low price knowing too well that such account can generate something good, just as you said this can only be tempted to newbies those who are too lazy to build themselves to grow up their accounts.
