Good but temporary. Big tech has your browser fingerprint against that plus LLMs will probably be able to match it again by text using cosine similarly.

Maybe you use tails everywhere and run what you say through LLMs to rephrase. Might be OK then.

oh I've accepted that. luckily I have GDPR on my side.

With that use case you either dont have enough anonymity, or will forget the number of identities and leave a lot of traces, like admitting you are in the euro zone.

I don't care about that much if I did I would never use social media and sit behind a VPN 24/7.
