I wonder if Google has a backdoor API which lets group people by backup email. If one always creates an account with the previous email as a backup, the link is east to make.

That would be especially useful for censorship services across competitors: Although Google Facebook and Twitter compete, sharing the flagged accounts would allow recognizing the same user coming back with a different email address.

who said anything about backup email

but sure? probably if you just alternate between a backup email tied to an email you use everywhere

New email per every service you want to use? It shouldn’t be this complicated

Sign In With Apple does exactly this — generates a fake e-mail address for each account, so the data harvesters never get your real one.

no. new email for the same service to make a new account, even after deleting your old account.

a lot of people dont know how or why they get the same suggestions of people and dont want that.
