>>73823440It's not even a real issue that goes against the law or anything per say, the most you can say it's frowned upon and taboo. And it's honestly ridiculous that it's only a thing in Vtubing only when in any single other performing arts career, this isn't a problem.
Are you worse off in life, for example, knowing that Chizuru Mizuhara from Rent-a-GirlFriend and Aqua from Konosuba are voiced by the same person, Sora Amamiya, who explicitly is credited with her real name in the credits? And does Kondasha and Kadokawa respectively have fits and start waving legal threats when she acknowledges playing both characters in public even though they own their IPs/characters 100%? The whole thing is dumb unless we're talking about the separation between personal IRL life and Vtubing career which should have a clear separation unless the person wishes otherwise. But even outside of those wishes, there's a lot that can be talked about before you get into clearly illegal territory.
>>73823884Tabloid/gossip magazines are a thing for a reason, people love to gobble that stuff up and Youtube is no different filled with that material. It's not a surprise it extends to Vtubing too. Best you can do is to turn off channels that do that, unfortunately, or watch the videos outside of Youtube to avoid recommendations.
