But if you don't want to leave a trace on Bitcointalk, don't create an account on Bitcointalk 
The whole "right to be forgotten" is dumb anyway. Many companies here require a copy of your passport and a signed request before they remove your data. Sending more information kinda defeats the purpose of being forgotten.Ordinary people should have nothing to fear, unless they engage in illegal activities, otherwise why would someone want to erase his traces from the internet, it's not like we're Satoshi to fear for our lives and vanish. Simply put, don't make enemies and don't scam people, you will be fine.
