Facebook is currently filtering out anything blockchain related which includes decentralization, ICO's, etc. I reached my friend limit several years ago and have left nothing but a steady stream of Steemit links since last September and virtually every FB post is now down to zero likes or an occasional like or two.
Perhaps they haven't figured out dtube.com or dlive links yet, but they will soon enough. This will probably have to go grass roots to be successful.
I have been actually gaining some followers on my FB page with my links. Perhaps they will crack down, but I will ride the wave out as long as I can. It's much faster and more effective for me than to try to convince people individually. I think people also are interested when they click into my profile and see that I am actually earning money on these videos. Nothing sells Steemit and Dtube better than Steemit and Dtube itself.
