I was never aware of these issues until I started studying Bitcoin.
formerly everywhere you subscribed or opened an account for some Internet service. We used our real names and data.
Today thanks to protocols such as Nostr we can more easily manage the identities that we want to be public on the Internet. and maintain our real and private data.
Today I use these services or applications that may be helpful for you.
None require your real data for use or registration.
These are some examples. I hope it is useful.
