The archived copy of the Hololive career page closest in time to this post is from March 19, which doesn't have a listing like this, although I did see a different job listing aimed at disabled applicants^[There were also paid moderator positions—wonder how long that's been a thing? Interesting to note that even though they were hiring moderators for Hololive English and Indonesia those jobs are only available through the JP portal.]. Would be nice to see some hard proof, but given that the only place I could find anything about it was this exact post across all their different social media accounts, I'm gonna assume it's just the result of taking some bad machine translation at face value (since obviously someone who would call Cover "a company operating Hololive Production" does not have a strong grasp on the subject matter).

It's played for laughs here, but if it actually were an accurate job posting, from the talent perspective that seems kind of chilling—like a prelude to your manager chewing you out for not hitting your KPIs because you failed to mention merch at least once an hour and cross-promote three brand deals per stream.

Sounds awful, you’d have to pay me at least 5 times that much to do something like that.

This is a hard job to keep + the vtubers are basically getting an undercover snitch so that their managers can chew them out
