Few days ago... my page's reach decreased a lot. I tried to figure out why it happened, and found that lots of people did 'hide all posts' and 'hide post', suddenly. See image Before that period, everything was normal and my reach was great. I think that someone is trying to decrease my reach with his bots. I want to mention that I didn't post any wrong content that caused my users to hide the posts. I kept posting the same type of content I am posting all the time, so there's no way it happened because the content of the posts. What can I do about that? how can I report that to Facebook and hope that they will take care of it?
