Who are the hivewatchers?

I've noticed that post are being downvoted from accounts assosiated with the hivewatchers account. Apparently, they are downvoting ANY content of the targeted accounts. The litle explanation I've found is tha they are doing this to account who are allegedly using third party content (which is pretty much what drives huge part of all social media platforms).

My question is: Who voted those people to be content police? Are they official HIVE content monitoring accounts or they are just a bunch of self-centered people who decided to play hive gods.

Thank you for you answers and please, keep it clean in the comments.
