Do you have any better reasons than stating your own opinion about account sale being against forum rules or not?

Here are mine.

Is breaking the forum rules against the forum rules? There are clearly stated rules for new accounts - posting limits. By using a bought account these rules are being explicitly circumvented.

Do you remember that bitcointalk was recently hit by a Man-in-the-middle attack and there was a warning on the frontpage about accounts potentially being stollen? And just a few days later there's this slick guy, posting from a new account, selling accounts for bitcoin? What will stop people from thinking that these are stolen accounts on sale? Feel free to call this a conspiracy, but how long will it take till people start throwing accusations, because this starts to look very much like the inputs.io "hack". If mods want to keep the spirits calm, I'd expect them to want to keep the account management process as transparent as possible and kick the speculators out of here. Or not. Up to them, their move.

PS: that thread seems to be deleted already.
