You're talking about Yuko right? Her recent ASMR member stream was nearly on par with Finana's more infamous ones.
I still feel like this lewd ASMR stuff is walking a very fine line that could backfire, especially being hosted on YouTube rather than an adults-only site. There's no two ways about it, you've killed any sense of plausible deniability when you're roleplaying with listeners while grinding on plushies: it's pornographic and your fans are masturbating to it.
I don't complain about this from a prudish or moral standpoint, I'd rather a world where people could create whatever they want provided no-one's hurt in its production, but the only reason it's allowed on the site is because YouTube's jannies haven't realised it's happening yet. As soon as it takes off as a "meta" (which it will, coomers spend money), advertisers will pull out because mainstream brands traditionally don't like being associated with explicit content, and YouTube will introduce knee-jerk policies and probably use automated bots that false-flag safe for work anime videos to satiate them.
