I've had it twice...the worst thing ever!!! I simply do not need to know that much information about everybody, and why everybody thinks that anyone cares to know that much about them is amazing.
I can't remember how I got off the first time, but I did....then, I had a niece that was going through some medical issues, and they way they kept people up to date was with Facebook....so, I re joined(with my go to nowhere email address) the texts on my phone nearly drove me nuts....the second time was easy....I just deleted the app off my phone, and that's that!!
they can send anything they want to that dummy email...I never look at it.
