Facebook may also collect information about you from other sources, such as newspapers, blogs, instant messaging services, and other users of the Facebook service through the operation of the service (e.g., photo tags) in order to provide you with more useful information and a more personalized experience.That's a little creepy. They don't say much about how they'll disclose the information they've collected. There were other places that were ambiguous, too.
For content that is covered by intellectual property rights, like photos and videos ("IP content"), you specifically give us the following permission, subject to your privacy and application settings: you grant us a non-exclusive, transferable, sub-licensable, royalty-free, worldwide license to use any IP content that you post on or in connection with Facebook ("IP License"). This IP License ends when you delete your IP content or your account unless your content has been shared with others, and they have not deleted it.
OK, so they aren't assuming copyright - that should be a gimme, but who knows in this world. Their intellectual property license appears to be reasonably eliminated - but what happens if some asshole refuses to delete the content? That gives Facebook the license? Facebook should then be able to tell that person to delete the content and remove the license. And they should explain that.
I never realized that Facebook's terms require real names. I've been thinking about seriously slowing down my website registration - truth is, it's easy to say now, but the websites always have goodies for the registree.
There should be laws stating that I can always ask a business to give me all the personal information it has on me. Then I should be able to look into destroying that information if I don't feel it's well-placed in their hands.
Notably, however, the Better Business Bureau's terms seems to be the worst of those I've looked at. They're short and ambiguous about key details: what can they do with my complaint information; what's up with the "only governments/organizations" can link? It's just not clear.
