You may be too young to understand this. I received a chain email that said you are now immune to any consequences of not forwarding, and still entitled to the benefits of all requests to forward. I feel no compunction whatsoever to even think about what someone online wants me to do. Frrreeeeeeedoooooommmm.
Younger than me. You may have missed the chain emails that are the same as the fbook posts, "post this on your wall and you will get everything you desire. If you don't you may suffer."
