Things are lost on the internet. Pages get deleted, not everything is archived. Working links don't work or are re-directed to something else. One of the reasons I got an extra hard drive right around the covid stuff was because I had a feeling there was a lot I was going to be saving.
There's stuff that can't be found anymore. For instance try searching "Strav" "Haggle and Rejoice!". It won't bring up any posts by me. "Haggle and Rejoice was a forum I participated in late 90's/early 2000's. It's still indexed by Google on voyforums...but all it is is advertising now, and the page history only goes back so far.
Here's an archive showing my username (Strav) at the time, although it doesn't appear any of the actual posts were archived, just the index:
https://web.archive.org/web/20011112100339/https://www.voy.com/14104/
As far as I know, that's the only proof there is that I even participated on that forum.
