Are they really "using" her, because honestly she comes across as someone who is saying a bunch of outlandish shit because she's desperate for attention...basically young teenager behavior....
It's really bad. I have an acquaintance in my feed that is alt-right (I met him through a high school friend of mine) and he and I have been engaging in a rather cordial discussion on his wall. However, there was a day or two where I am not sure what happened but some sort of Facebook algorithm malfunctioned and I started getting the most vile extreme alt-right, neo-Nazi pages in my suggested pages sidebar. Some other things too, like extreme right-wing news sources in my trending feed...
My facebook is back to normal now but it's honestly scary as to how much is filtered out. A lot of it is truly offensive.
