If you are passionate about politics, chances are you will end up trying to help someone with a Facebook page. Every political page is going to have trolls. Don't try to reason with trolls. They feed on every reaction. Just block them, keep blocking them, and don't feed the trolls! No good can come of it.
Step One: Click Settings at the top of your Page.
Step Two: Click People and Other Pages in the left column.
Step Threee: Search for the person or click to check the box next to the name of the person you want to ban.
Select box next to troll's name, click the cog/spiked wheel/locking washer looking thing, and select "ban from page."
If you are still having problems, ask for further support on our group page HERE.
