Account sellers may have purchased the account for resale and are not tied to the scam, but if an account scammed they fall into the collateral damage category as well. It's the account that gets ruined, the seller themselves may have nothing to do with the scam.
Again, it should be looked at as case by case, if the seller was not in control and didn't do the scam, why tag them? Aside from the fact that people dislike sellers. The account that the scam was done on is what should be tagged.
Its a whole mess of a topic for sure. My mind could be swayed and its a subject that we will never get 50%+ of the masses to agree on.
You are always wise and have broad views. I absolutely agree with this, everything should be based on a specific case. Maybe it would be better if we could propose to the forum to ban trading accounts so that if someone buys an account then it is clear that it is a violation. Until now buying and selling accounts is still legal in the rules of this forum.
