Honestly, this should never be allowed.
It’s archaeology-hostile. It pisses me off to no end when I am searching for information on reddit and come across people replying to deleted posts by some paranoid user who wishes comments were more ephemeral like Snapchat.
This is what the next dark age of mankind will be like, people from the future looking for historical information and finding nothing but deleted or decayed data.
Here’s a tip: if you don’t want something to be up for all time, don’t even bother posting it. Keep it to your self. There are a lot of damning things and incidents that could end people’s careers and reputations that I’ve never posted about because I do not want the permanent liability.
I feel like the art of staying anonymous has been lost on people. It’s not that hard.
