Everyone's got skeletons in the closet and anyone, at any time, could have them paraded out in front of the whole world for their fifteen minutes of shame.
I still believe strongly in privacy and keep my communications safe! And at the same time, I fully expect that, my whole private life will be made public, and that haters will gleefully smear the entirety of it with utter bad faith. This is good, actually. Anyone who does this wasn't worth associating with in the first place, and showed their lack of quality. So their opinion of me can not possibly matter at that point.
This is the only sane position.
Some more good news: social media has so thoroughly desensitized us to scandal that at this point, there's nothing in most people's histories that would make a wave, much less be remembered after 24 hours.
The only thing you have to be ashamed of is shame itself.
Another way in which cancels, doxxes, normalized DM leaking etc made everyone insane:
Nobody believes in privacy anymore. Young people literally don't believe it exists as a concept
They (mostly correctly) understand everything they say, post or DM can be saved and circulated to hurt them later
This leaves the average person (who lacks supernatural ability to discern someones trustworthiness) with 2 options:
1) Never say anything serious or real to anyone
(This prevents you from making friends and causes you to go insane)
2) Accept that every part of your life will be known by the public and become a livestreamer or something
(This prevents you from making friends and causes you to go insane)
