Social media and the freedom of speech continued

After experiencing being cut off my from my online social group because someone apparently saw fit to mass report me, some questions came up.

What is mass reporting? How does it work?
How many people does it take to mass report someone? Who investigates those claims that people are indeed violating facebook rules?
What happens if it is found out that people have unjustly used the reporting feature in order to suit their cyberbullying agenda? Are those people banned? Are their accounts shut down? 

A lot of questions, and where is that facebook security you can turn to if you feel someone is engaged unjustifiable mass reporting activities on your account? 

Mass reporting is enough people reporting whatever comments, pictures of post you upload by using the report feature on the community standards page. 
You are given options like this person is impersonating me/someone i know/a celebrity etcetera, and among the options are also 'this person is annoying me' and 'this person is harrassing or bullying me'. Interestingly, if the person is only 'annoying' that's that, but if the person is harrassing or bullying you are given an option to mail a copy to someone you trust on facebook - so I did in one instance, I forwarded my blocking of one person to a facebook friend and fellow volunteer who lives in Britain and hasn't been on that community page where I got reported (200 % by someone from the counterpart of that page which happens to use almost the same name but with a twist), I also sent her an e-mail explaining what happened and asking if she was okay with me turning to her for help. This feature was only recently installed by facebook.

But how many people does it take to mass report since that other page had only 177 'likes' at the time, and only between 8 and 20 people who were active on that page?

One of the first sites that seemed to provide some answers was this one:

but after going over it, I didn't find much that was helpful in my situation, though knowing that it is taken seriously by authorities is reassuring.

Back to the safety centre it is.

And there it is, the Facebook security page. 
I am reading a host of comments by other posters, yet as I am blocked I am unable to ask for help. So I guess I will have to wait until the block is lifted...
