About me:
I’m just getting started, deleted almost all my Google accounts, deleted my Reddit account, I’m deleting my Lemmy account too. I’m pathetic, unfortunately I was unlucky enough to be born with a good brain, I don’t even want to tell you how I screwed up, it’s not that scary, but I’m ashamed, I’ve, for first: linked multiple accounts with my phone number. For second: on different accounts, I have a similar pattern of communication with people. They were tied to e-mail, fortunately I did not give my phone number to those e-mails.
I’ve almost never used a VPN, never used Tor, and it’s not surprising, my brain is lousy, I constantly forget where I left the keys to the house.
Therefore, I would be happy to receive advice from those who also delete themselves from the Internet or have already deleted.
It depends on how unique you are.
If you have a name like John Smith, you can scrub your content and reliably hide behind all the other John Smiths out there.
If your firstname+lastname is unique on the planet, you have a uniqueness problem; there is no-one else to hide behind. You can also scrub the objectionable bits, but a good secondary strategy would also be to blast bland/irrelevant/dummy content everywhere such that anything important gets lost in the noise. You don’t want the few important bits to come up first in a search - make them work for it well past the 100th page of search results.
