Or ignore their crap. Which I do.
AFAIAC FB is a tool for sharing pics of your dogs, your hobbies, grandchildren etc.
I have suggested to a couple of friends that FB is not the place to demonstrate their conservative ideology. FB/Google are far too leftist and nosy, as well as being a haunting ground of the US intelligence Stasi. After thinking about it, they agreed it was prudent.
Most folks I know pretty much have. But, think deeper. Social networking sites change and morph, but these tactics are available to the operators and now that they are public knowledge, the question is what should be done about it?
Imagine Google shaping the queries you do on their search engine, not just by whom will pay for “placement” but by how they will manipulate your thinking and opinions?
