Remember the good ol' days when we all thought that everything on the web would exist for eternity and over.
Now people don't give a shit about URLs. Webmasters casually move files around all the time because they feel like it, and if links get broken, who cares, that's the referring site's problem! Their beautiful file hierarchy is more important than the web staying connected!
That random 20 year old video of some middle schoolers doing a flying kick and breaking a vending machine? Yeah, just popped up on my feed yesterday.
