Bingo. I've told this story a few times on here, and I feel the need to tell it again whenever the notion "uncensorable internet==unqualified good" comes up:

Once I got doxxed by bloggers from one end of the political spectrum who thought I was a blogger from the opposite end. (We have similar names, but the doxxers put out all of my info. I generally try to avoid making extreme political statements publicly on the internet.) Even after I got my info taken down, someone archived it and the archives got passed around on Twitter, prolonging the mess. Even now all that stuff shows up if you google my name (which I could see being an issue in employment and housing searches, for instance).

I'm not asking anyone to care about what happened to me, I just want people to think about the consequences of a system that can't be moderated. If some bad actors can continuously re-inject false information about normal people into the internet, it can have negative effects on the lives of those individuals. Advocate for an uncensorable internet all you want, but you should also be honest about the potential ramifications.
