How do you block a contact from the new messenger?

How to block a contact that is not on your Yahoo messenger?

• Hi, I has some contacts on my Yahoo messenger, however, suddenly some of my contacts disappeared. I added all the contacts that I lost except on contact. That particular contact still sees me when I'm online. How can I block this contact when his ID does not show on my Yahoo messenger, but my ID shows on his messenger? Thanks

• Answer:

  You must delete the contact from your Messenger List in order to ignore them. When you ignore a contact, you always appear to be offline to the contact. They can never view your status or send you an IM. To ignore a contact: 1. Click the "Messenger" menu in Yahoo! Messenger and select "Preferences." 2. Click the "Ignore List" category. 3. Select the option labeled "Ignore only the people below." 4. Click the "Add" button. 5. Enter the yahoo_user_id of the contact you want to ignore. 6. Click the "Ignore" button. 7. Click "OK" at the bottom of the window. You can ignore up to 100 contacts. Please Note: You can remove a contact from your Ignore List by selecting the yahoo_user_id and clicking the "Remove" button. To ignore anyone who is not on your Messenger List: 1. Click the "Messenger" menu in Yahoo! Messenger and select "Preferences." 2. Click the "Ignore List" category. 3. Select the option labeled "Ignore anyone who is not on my Messenger List." 4. Click "OK" at the bottom of the window. Source(s): http://help.yahoo.com/l/in/yahoo/messeng%E2%80%A6
