I discovered that Facebook is ghosting comments / post not only by spamming but also by sharing/discussing about "unwated" stuff. Whenever I try to discuss politics, refugees crisis or something with censorship, my comments got ghosted and nobody will see it but me. I tried for example to share this video https://www.youtube.com/watch?v=44vzMNG2fZc with 8 accounts one multiple fb pages and it got ghosted. I am afraid of upcomming totality when if you don't have the "right" thinking, you will get censored or muted :/ Or I also tried to share this http://www.timesofisrael.com/most-israeli-jews-agree-africans-are-a-cancer/ it also got sometimes ghosted (within couple of seconds, so no one could report it). Maybe just my accounts are ghosted, but it is sad.
