Even today, there's still an ongoing rot of most online content--especially that not connected to a True Name. It isn't truly lost or anonymized but it gets pretty hard to mine over time.

That said, I'm glad that nothing of mine pre-college is online and everything from school that is still public went through an editor. No photos of me doing anything remotely scandalous. Even everything from BBS days is likely gone though there was nothing too exciting even there.
