Go to the Banned Users tab.
I know, it is confusing going to the Banned Users tab before you have even banned someone but that is where you have to start! Go to Settings, click on Banned Users, and you should see a box that says ‘Banned’. Click on the arrow, and change this to ‘People Who Like This’. This will bring up a list of everyone who likes your Page.
Find the person you want to remove.
Click on the arrow next to their name, and select ‘Remove’. Once you click on this, you will also be given the option to permanently ban them.
If you didn’t mean to ban them.
Finally, if you find you’ve mistakenly banned someone and would like to remove the ban, simply go through the same process, but select ‘Banned’ from the drop down list instead of ‘People Who Like This’. Click on the arrow to the right of the person’s name, and you should see the option to unban them.
And that’s it! Hopefully this isn’t a process you need to do frequently, but don’t feel bad blocking or removing fans who are just out to cause trouble. Better to keep your Page a safe, fun and informative resource than to let someone stir up trouble!
