What is the legal notice of settlement of class action from facebook?

[Sarah]

FB used information about people who liked certain things as ways for ad revenue. Every once in a blue moon the side of the page said "so-and-so liked this. Like us too!" or something similar and FB would get paid if you clicked on the ad. They used photos and profile information about the users who liked the pages and made money off of it.

The original emails sent out are legit. There are now some circling that are not real. A link should be in the email stating that you need to claim your part of the suit before March something. When you click on the link it will ask for your name (or the name attached to the account) and other information about the account. It takes about 5 minutes to fill everything out, if you don't read any of it. If you feel like taking the time, which I'm guessing you may not considering you posted this before searching for the tons of other questions just like it, you can get up to $10 from FB. If too many people claim part of the settlement, then FB will donate the money to a non-profit charity in the names of those who claimed the parts.
