These are some good points and I don't think till now I saw any topic like this before so yeah it's a good topic for everyone to avoid buying and selling accounts. What's the real point in buying accounts besides the buyer wants to get accepted in some campaign. He/she won't learn anything like you said a newbie buying hero or legendary rank account and asking about newbie rules like merits, activity, or what BTC blockchain is then that is total disaster.

Then to save themselves they will use AI and will get caught easily. To be honest, I did not saw much cases about people getting caught after long time that they aren't the real owner although saw some topics started in marketplace where they tried to sell account and I saw one site too where they listed accounts (not details) but only rank and price.
