Let’s say an individual posted identifying or incriminating information online, inadvertently or intentionally, in a public place.
Then a third party decides to store it, and possibly make it accessible to others.
If the original self doxxing user then pulled the original dox, but was unable to scrub the rest, would that information still be considered public, or would it be private? Was it ever truly public? Or private for that matter?
The tricky part is dealing with inadvertent or malicious (i.e. some other party), posting of private information to a public space. That's really hard to deal with on multiple levels.
For one, the archives would retain the information and scrubbing it is effectively impossible.
Secondly, legitimate things which should remain public (i.e. were posted publicly, are of public interest, etc.) can be argued to have been inadvertently or maliciously posted. So you need some way to moderate and create rulings for each individual case, which quickly becomes untenable due to the sheer volume of information being posted and the inordinate amount of time required to investigate vs. post.
