You can use “TMAC v6 Mac address” changer
https://technitium.com/tmac/
It is free and will change the MAC address that some sites use to track you. Example is Reddit. They ban you by account so if you get a new one you will find you are banned right away but if you change the mac address then that new account will work until your banned by some moderator who does not like your opinion or by Paramount as happened to me when I criticized their new Star Trek shows. I was banned site wide and not just in the r/star trek one. Turns out Reddit gets paid by them so they become ban happy.
Thank you. Yes I knew about changing MAC addresses. It is all the other data they are mining that is the real problem.
