If you find yourself the focus of some very unwanted attention, you can block that person from messaging you in the future. (While it does not prevent you from seeing the member in searches or on the site, you won't receive any future messages.)
- Access the last message the member sent you.
- From the menu, select Block This Person.
If you have a change of heart, or they have a change of personality, you can always unblock them. Head over to Edit Profile > Mail Settings or use this link and view your list of blocked profiles. Select the person and unblock them to welcome them back into your life.
