> Nothing will stop stalkers from crawling stories with archive.is or even just taking screenshots.
What stops this is not being interesting at the time you post. So if you're some random high school kid in 2020 who posts something stupid, nobody is going to obsessively catalog what you say in case you become an NFL quarterback or a congressperson in 2030.
That was true of the old internet, and might possibly be true still, but not for long.
Nowadays we have archive.org and people who wish to datamine and hoard things. I can absolutely see someone coming out with a search interface to browse through peoples' Twitter stories that they've secretly been archiving for years with a small bot scraper. The guy running archive.is has been spending thousands of dollars a month to run it for ostensibly no reason whatsoever.
The rules have changed and the stakes have escalated. I think the world will wise up and we'll start seeing greater opsec efforts around personal anonymity. People will start acting online like they do in real life in any situation that they even remotely care about (even under their pseudonyms), and anonymous communities will continue to grow and thrive as the outlet for all of the hatred that people harbor.
Not even really true of the old internet, depending how far back you want to go. Remember there are entire archives of Geocities, and everyone was frantically archiving the entire Yahoo Groups. There was the Dejanews archive of Usenet, and so on.
The idea that "I'm not important enough" needs to disappear. It doesn't matter if you're important or not to automated bots.
