Watch Twitch livestreams?

I wanted to watch the old streams of papaplatte from 1 or 2 years ago somehow, but not on twitch I think where can you look them up?

Then they no longer exist.

Twitch deletes the stream after a certain time (from 2 weeks to 2 months depending on whether you are a partner or not. You can only see if someone has uploaded it to YouTube. Otherwise the streams are gone.
