Note: Blocking messages from someone is different from blocking them on Facebook. If you block messages from someone, but you don't block them on Facebook, you'll still be able to see their Facebook profile. Depending on their privacy settings, you may also be able to see things like their status updates, comments, likes and tags on Facebook. Learn more about blocking people on Facebook.
