According to the recent discussion I was having with a friend, he said that the output of AI is based on preexisting data, and if the results of AI are properly checked, you will always find a thin gap between the original data and that of the AI. In this case, I don't agree that your account should be tagged, if you decide to retire, there are still ways to keep your account free from AI.
I looked at the account of
Satoshi which was last active on December 12, 2010, and has not made any posts since then and no tags.
You don't need your account to be tagged, you can just create your last thread and tell the community that you have decided to retire; then your account can be placed on archive by admin, and no AI can act in your absence.
