Sorry it's not actually from Facebook, but there didn't seem to be a better community for it.
I live in a neighborhood with a large elderly population, and we all got one of these in in the mail today. Looks like they're not just satisfied with recruiting people into the conspiracy theory cult from Facebook and YouTube anymore...
I could see a lot of people falling for this, thinking they've been out of the loop from not having the internet.
No website or phone number?
