When I get an outrageous forward I always check it with Snopes.com. When I find one that is simply not true, I usually send a polite message back to the person who sent it to me with a link to the Snopes.com post that debunks it.
Last night I received a forward about a "Hotelicopter" which included photos of the alleged flying hotel. A quick check with Snopes yielded this information.
I imagine most people are familiar with Snopes.com, a site I used frequently when I was a working reporter. E-mail forwards may be contributing to a dumbed down America, one that believes anything it receives in the mail.
By the way, I never forward, even when it has one of those "please send this back to me to show me that you like me too" things. Nothing personal meant. I wish all of us would check out these ridiculous forwards and do our part to stop the spread of false information.
