Is the email notifications not working right now? I won three / lost one auction today on eBay and didn't recieve any text messages to my cell phone...
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 .
