I want to create a new online identity that isn’t linked to my previous one, but I’m confused about what can still connect the two. If I make a new email on a device I previously used for old accounts, could it become linked to my past footprint? What if I use a freshly formatted device but the same Wi-Fi, does that still create a connection? I assume I should avoid mixing old accounts, usernames, or services with new ones. And if I pay for things online with my card, does that link identities too? I don’t want to start over and later realize the new identity is still tied to the old one. And what about stuff I can't make or don't want to make new accounts for/linked with old accounts (e.g games).
