Bulk email

I received that email about the class settlement and what is this about? How come i got an e-mail? I’m so confused about everything. I don’t want to be a part of this, but they said you can opt out of it, but i don’t want/need them knowing my address. Facebook doesn’t know it know nor should they. Can some explain what is gonna happen!? or what is even going on?

once there’s some one wrote you a message or some on your wall, you’ll be receiving an email notice. What’s the detail step to opt out this function?????

I checked the opt out of email option thingy so now I’m wondering if everything will be normal, like I’ll still get all the emails, if I sign in with the same email….
Yah I don’t WANT to reactivate it besides it’s almost past 14 days…
