Upload anime on youtube without copyright

So I've seen a shit ton of channels who post anime (long clips/episodes) and they are monetizing the videos.. Is anyone here who experienced it or know how to take off that copyright off anime clips?
Here is an example channel of what I'm talking about: youtube.com/channel/UCd21m0AHf4Vx88Znty7v4Cw

Any help will be appreciated :)
(Hope I posted in right forum section)
