It’s easy, use a VPN and as many fake data as you can, also you can use an AI generated profile pic, if you need a phone number you can use a virtual number like TextNow app.
OpSec fail, never ever use any personal info when you are dealing with something you don’t want to be indentified for, it include obviously recovery emails, usernames and passwords.
If you want anonymity and the advantages of a VPS VPN at the same time you should look for a provider which accept crypto payments, and optionally setup tor, i2p and freenet nodes to obfuscate your traffic.
That way you will be helping the community and at the same time securing yourself.
I use it, it works pretty good tbh.
