Not gonna lie, I'm kind of exhausted thinking about that method. Is that how you operate? I'm guessing it gets easier over time.
Yes it gets easier. It's easier now with NOSTR.
I had to start over because of KYC link between my meta id and IRL. Hard to find, but the right person with the right skills could have doxxed it.
But that link is now broken. And I learned a lot about how keep the two id completely independent of each other.
Just add one thing a time. Creating a new email for long usage on your phone? Install new browser, never their app. If you have a standard android, you can create profiles. Google will still know but that's another step.
