How can you block someone from sending you a text message from their cellphone to your yahoo messenger ?

• I have someone who keeps sending text messages (sms) from their cellphone to my yahoo messenger and I want to block them from sending them to me cause I don't want to recieve them anymore ever.

• Answer:

  To ignore someone, click the Login menu and select Privacy Settings. On this screen, you can add the IDs of people you wish to ignore to your list, or you can choose to ignore anyone who is not already on your Friend List. You can also click the Ignore User button in any instant message window. Note: If the Ignore User button is greyed out, this means that the user is on your Friend List. You must delete the ID from your Friend List before you can ignore that person. After you've ignored a person, he or she won't able to send you instant messages or see whether or not you're online. The person will stay on your Ignore List until you take him or her off, so you don't need to ignore the person each time you come online.
