Also wouldnt be so bad for these insanely successful vtubers to pay a little extra for the artist to post it later.

If not requested and the artists puts it in their ToS it's entirely on the client for not being aware of it. But, i also don't see why people have such a hard stance on not waiting to post because they did reserve the right to do so. Do they just want to make sure they dont miss out on exposure?

Stop posting and open Minecraft Server
