Sometimes people also share sensitive information out of ignorance. Perhaps there was a time where they did not know any better?, which reminds me of that one user who posted a selfie with his passport... What bewildered me was that he didn't mind posting such information because as he said, "all russians are doxxed". Even if that was true, it makes no sense to deliberately share such information to a new audience.

If one has posted sensitive information, I can understand if they wanna 'take a chance' of minimizing the damage by requesting deletion.
