Some of you may be familiar with the YouTube channel AnimeUnity. They are a popular YT channel which re-uploads AMVs and has a huge subscriber base. Historically, most AMV editors don't seem to mind it when their videos are uploaded here; besides the large audience, the channel creator gives credit and links to the editor's YT channel.
However, recently AU has decided to start monetizing videos on their account, meaning they are getting paid for the content on their channel. Besides the hugely questionable decision to do this and not distribute payments to the people whose works they are hosting, there's the significantly more worrisome issue of the legality of this in the first place, whether they are the content creators or not (they're not).
In addition, from what I understand of the situation AU is going to sidestep any legal liability should the content on their channel come under fire (and let's be honest, it's likely this will happen sooner or later) and put it all on the content creators. I personally would highly recommend messaging AU and asking them to remove your video(s) from their channel if they've uploaded anything of yours.
Also, here's some entertaining reading material between AU and Koopiskeva, which pretty much highlights how many editors I know seem to feel right now.
I may be missing some key details, or be misinformed on some things, so other editors please feel free to chime in if I'm mistaken anywhere.
