There's no guarantee that your data is actually being deleted by normal social media platforms. You're worried about your wife finding out about you but you're giving out your identity to the 3 letter agencies. Isn't that worse?

That's an interesting observation. On one hand, a hypothetical unknown penalty of uncertain magnitude because information that may or may not have been deleted falls into the hands of an alphabet agency (or just Alphabet) and is then discovered to be used against me.
On the other hand, my wife figures out enough about nostr to view my npub note history, or convinces me to show her. She is an insecure person, prone to jealousy and often feels slighted over the most innocent of interactions.
Do you see why one seems to be a lot more realistic and likely? It is almost like - there might be pain vs there will be blood.
I exist in a world that bleeds, but I try to keep it to a minimum, mostly.
But no, I don't doubt that anything I post anywhere is being catalogued by those I have not given permission to do so, beyond the simple act of committing it to digital memory at some point. Deletion of digital information only serves to obfuscate it from those not trying hard (or smart) enough to find it.
