This is about the answer I expected. It is impossible to prove that the account was sold, and if nothing besides the sale contradicts the rules, then there is nothing to add.
I will not close this topic but i got answers on my qeustions, thanks
If somebody want add something go ahead.
It’s not that account sales breaks any of the forum rules. It’s just that most members believe that accounts that were bought can be used for unethical purposes like someone could buy an account that was active in the collectible section and has completed several threads with other users and because of that they have managed to earn some reputation for themselves if such an account was to be sold, it would be easy for the new owner to use the account to scam the community since a lot of people already trust the account.
And just like the post above mine stated, this very account is not active they don’t even have an interest in joining a signature campaign but I’ll still advice that you keep a close watch and if you suspect anything then you can come back and warn the community about it.
