*Anything you post on the internet, the real, open internet, is forever*
I've tried looking for stuff I posted on craigslist 5 or 6 years ago and nothing was in the wayback machine, only dead links to a few posts.
Apparently the crawls of the site only went a couple/few layers deep, as well as crawls not being conducted daily, and some years had only 2 or 3 crawls for the entire year.
I haven't tried searching my old facebook posts yet though, maybe some sites are more thoroughly catalogued than others.
Perhaps some other entity is storing my old posts, but I doubt that the NSA will allow me to access my own data.
