I know a lot of Phase girls get saddled with the menhera thing (and to be perfectly honest, they fucking are) but it's often all in good fun. They appreciate their audience, and try to show it to the best of their abilities.
In NijiEN, you have Enna calling her own followers cucks, and it really didn't appear to be a bit. In fact a lot of the shit I thought were bits weren't. I know there are lots of spineless faggots that will take shit like this and ask for more, but there's a limit for those that just watch for "le funni anime girl" crap because it's the way we decompress from everyday life.
