Huh, Hololive Gamers tag is in general instead of Copyright. Odd.
It's because English, China, and Indonesia are regions. Gamers, Holofive, and Fantasy are groups within the JP Hololive region.
This setup does mean that the JP branch doesn't have its own separate copyright tag though. As well, Holomyth was nuked as a tag, and will probably need to be remade if Hololive English gets more generations. The couple of JP Hololive generations without names also don't have their own tags, either.
Not exactly. We treat those tags like LiPPS and New Generations in Idolmaster Cinderella Girls. Holomyth tag is not nuked and is (should be) used when all 5 members are involved in the picture, or the author indicates mentions the words "holomyth" in the picture or its commentary.
