There was a great fan-made film clip to a John Zorn song that was on YT for years. Then one day, gone. Erased from the internet a magnificently disturbing piece of artistry.

Luckily I downloaded it, but that means in time it'll cease to exist. I could re-upload it, but that feels like an invitation to have my account terminated with prejudice.

For me those were some viral videos from the older internet. It is not because those videos violate YouTube policies or anything. The uploaders just closed their accounts. Some videos just exist in my memory now.
