Taggin' controls
Previously, we talked about a new feature that allows members to block people from embedding things in their profiles and comments. Similar functionality is now available for tagging.
Through your Account Settings, you can now control who is able to add tags to both your uploads and your profile. You can choose to allow only your friends, everyone, or no one at all. If you are having a problem with people tagging your uploads with words that you do not feel describe your content properly, simply turn public tagging capability off, or switch it to friends only.
