MSN Block Checker
This block checker will allow you to check block status of your friends in your MSN messenger contact list.
Simply enter e-mail address of your friend that is added in your contact list, and press Check Block button. This tool will show you status of block! If you get the word "BLOCKED" it means you are blocked by your friend. If you get "NOT BLOCKED" it means you are not blocked!
Some time server may be busy and show you "Unknown Status"! In this case please retry to check block status!
