That actually is really strange, and I felt odd watching it. Maybe something's really going on there.

Having said that, it could also be the case that she's just been feeling stressed out by the success of her own channel and the heavy responsibility of living up to fan expectations, which she's been failing to do to the extent that people have decided she's being held hostage by a gang of creepy thugs.

If she was just a normal person who had a bad week, and people started feeling that she was different from her "normal self" (as if they know what that is) to the extent that they start a Twitter campaign to save her from imaginary abusers, that would probably make it pretty hard for her to get back to her normal self as well.

Conclusion?

No idea.
