VRChat-Tagged Posts Revisited

So I came upon post #7431989 and I was curious about the reason for the disapproval and deletion.

I've consulted with topic #19190, and while the subject is a Blue Archive character, it is a recorded clip from VRChat.

Even so, since it is from at least one copyright, shouldn't the post be retained? Or is such clips against Quality standards?

Doesn't matter the character depicted, a VRChat clip isn't the kind of content for Danbooru

Looks like we need a meta tag for VRChat recordings.
