I don’t think so, I think people are more concerned with having tools to switch their username/posts/comments from one server to another.
Also, in general, if you don’t want it “on the internet too long” you probably just shouldn’t post it. Anyone can scrape that data in the time it was posted. It’s never really gone if someone else doesn’t want it gone. *shrugs
Even though this is top comment, this is an underrated answer.
