The opposite of a Friend is someone you do not to want to communicate with. You can place such a member on your Ignore list. You can prevent single members from commenting on your photos or profile by assigning them the Ignore status and thus deactivating the comments function for them. Other means of contacting you (QuickMessages, Private Messages) will also be deactivated for these users. This DOES NOT chancge their ability to contact you on the forums and via PhotoMail…
This function should be used in the rare case in which a member repeatedly sends harassing messages or uses a discussion tone that cannot be tolerated under your pictures and does not stop even after you have asked him to do so.
