No, only corporate VTubers are forbidden from saying publically that they are said VTubers, but two things:

The way Youtube's algorithm works is that it includes the metadata of the videos themselves, ala if a corporate VTuber uses the same computer for both her VTuber channel and her non-corpo channel, the algorithm will occasionally recommend the non-corpo account. That's what happened with a lot of people.

The other thing is that voices are very recognizable, which is why for example it was very easy to tell that IryS of Hololive was Namirin as an example, who has one of the most viewed cover songs of all time on her channel.

But having seen multiple VTuber's IRL accounts, he's right, the majority of vtubers who have IRL accounts are very attractive, they chose vtubing either for the sake of security, the low self esteem bit, or just because they like anime a ton. Kson, formerly Coco Kiryu of Hololive has said the reason she ended up as Coco was because she wanted to be able to stream without doing her makeup first, and she's hot as fuck, to the point where she went to audition for a cameo in the latest Yakuza and got in over several models and JAV actresses.
