>>22038832Looking at it about 15 minutes later, it looks like Susan fuckery, not bots.
Her CCV was on a downward slope, and if you line it up with before the drop and 15minutes later, the slope looks consistent with what was before the drop.
TL;dr
Susan's new fuckery is to gank your viewership and then take a whole FIFTEEN MINUTES to give the viewership back.
Fifteen minutes. For a Susan gank.
I hate youtube oh so fucking much.
