Ask HN: Bots in YouTube Comments

I subscribe to a few YouTube channels and noticed one in particular has had a recent explosion of bots in the videos' comments section.

However unlike a traditional spam bot posting links or other advertising (like you would see on HN if you browse with showdead enabled), the purpose here is a bit unclear. The bots all fit a similar profile - they are young attractive females with Hispanic-sounding names that leave generic pleasantries or inoffensive non-sequiturs. Due to the channel's niche subject matter, a person fitting that description is probably the least likely person on the planet to be a subscriber so they stick out like a sore thumb.

I'm trying to understand what is going on here, since they simply add noise to the comments section. One theory is this particular creator - who is vocally obsessed with viewers and hit count - has purchased bots to artificially increase the views, and these comments are a method to evade Google's anti-abuse software by posing as legitimate viewers leaving innocuous-sounding comments. Does anyone have any other ideas?
