I’ll try and answer seriously, with some non-exclusive options, in no particular order:
Feeling ashamed, mostly because they’re realizing they’re either wrong or sounding stupid.
Not wanting controversial stuff related to them to be “saved” for others to find and use for scrutiny.
Honest mistakes (wrong community, thread, etc.)
The post becomes a cesspool in the comments.
Other personal reasons (feeling threatened, wanting a clean inbox, question got answered and they don’t care about historic purposes, etc.)
These are just my guesses though, and I try and not delete anything personally. I’m aware that anything I put on the internet will be immortalized, and that the healthiest thing I can do is own both my mistakes and my opinions, even if I’m convinced of my stupidity or ignorance at a later time. I’m only a human after all, and doomed to talk before I think. Best I can do is to learn as much as possible from it, and hope that others can also learn from my actions.
