Here’s a little article about Facebook censoring a questionable social network that has posted links to itself on Facebook. https://boingboing.net/2015/11/06/facebook-is-censoring-links-to.html
That’s fine…but posting that article on Facebook is also censored because it mentions (but does not link to) that site. That’s a problem and another example as to why we need to control our content and why I’ve started posting much of my media here first. I highly recommend you look at something like Known (www.withknown.org) Whether you use their hosted service or host it yourself (the best option). It’s something we should all be moving towards.
