I don't fool with any of those so called social media things. There are non-liberal places I like to visit where you can have good, real, discussions without the lies about the things you post.
When you block a person, they can no longer invite you to a private message or post to your profile wall. Replies and comments they make will be collapsed/hidden by default. Finally, you'll never receive email notifications about content they create or likes they designate for your content.
Note: if you proceed, you will no longer be following .
