... I am trying to send my personal data bitcoin.org (I'm assuming this is a legit site, correct me if I err) requires to get into their system to buy and sell bitcoin ...
Huh, I wonder how many new users buy bitcoin this way? (i.e. via
https://bitcoin.org/en/buy)
I'm guessing that a lot of new users might feel like this is the "official" way to do it (even though it's just a "MoonPay" widget).
That would be a great page to educate people about P2P exchanges and give them a couple of choices (Bisq, LocalCoinSwap, hodlhodl, etc.)
@OP: I've never bought bitcoin this way, so I can't offer you any help, sorry. You should be aware that there are many different ways of buying bitcoin and that some of them don't require you to share your personal info.
