There are various web application that is able to reveal invisible Yahoo Messenger user, XEEBER and Invisible scanner are the better ones in the market, its free!As for MSN Messenger, there is only one tool available, the Show Invisible MSN Messenger Status detector, it reveals, finds, and detects you and your contact lists MSN information and inform you all you want to know about your contacts. For example which person deleted or blocked you.

For those who are curious about which of his/her friends deleted or blocked them, do give the service a try but be cautious, I believe the tool is meant to be some sort of email harvesting application or another email hijacking tool created by spammers. Give it a try but remember to change your password as soon as you’re done with it.
Rule number one, never reveal your password to other company besides the original service provider.
