I recently joined to send a message to someone, about 2 weeks ago. I had an account years ago, but it was apparently purged. I get an email today informing me I've been suspended, oh the horror. The only thing I did with this account in the last 2 weeks was delete a notification today from Facebook about adding friends or whatever and only because they kept sending me emails about it . They have an option to disagree with suspension and I get to this page:
Upload a photo of yourself
Upload a photo that clearly shows your face. Make sure the photo is well-lit and isn't blurry. Don't include other people in the shot.
We use this photo to help us check that this account belongs to you. We'll delete the photo once we've done this, and it will never appear on your profile.
... and yes I was double checking the URL's. It's legit.... what a joke. I was half tempted to send them a picture of my middle finger.
