Account sales can't be banned because they can be facilitated off this forum and you may never know what deal has gone through and where. How can you control something that doesn't happen within the reach of the forum??
No, you are wrong. Account sales
can't be stopped, but they can be made bannable. If we make this a punishable offense, this introduces a huge risk to both parties involved in such trades. I'm pretty sure that this would have a decent effect on this though.
What's wrong with account sales as such, and how are they particularly different from any other sales? Of course, sold accounts can be used for something considered illicit (for example, spamming) or just outright wrongful (for example, scamming). But, on the other hand, Bitcoin is also massively used for illegal activities, though I don't see many people here calling for banning Bitcoin sales

One should never forbid what one lacks the power to prevent
