Oh I'm very much aware of it. Anyone's relationship with Facebook is governed by their TOS, nothing more. Because it's a 'free' service, you're not owed anything by it. In fact, you're the product. Facebook wants to be the world's largest walled garden and their entire revenue model is based on keeping everyone trapped inside it, for the purpose of selling advertising. I would never encourage anyone to rely solely on Facebook to publish anything they care about, no matter where it is on the political spectrum.

You can use it as a tool to reach more people but don't become utterly dependent upon it, that's just foolish.

Expect and plan for anything that you pay $0.00 for to disappear at any time, for any random reason.
