The SPAM stops here

"Superstition, idolatry, and hypocrisy have ample wages, but truth goes a-begging." - Martin Luther

I don't understand it. I'll receive forwarded messages from well-meaning friends and family members claiming one thing or another, but when I respond to them, I get blocked by their ISP as perpetrating SPAM. Why is that? Why not vet these messages at the source, and not the rebuttal? Why not filter out a message that claims that Pepsi is a godless corporation who doesn't have the balls to put "One Nation Under God" on their cans, instead of filtering the rebuttal that it wasn't Pepsi who did this, but Dr. Pepper, and those cans haven't been available since 2002? (Here's Pepsi's statement, and the Snopes article). Why is it that rumors that Barak Obama is a radical muslim get free reign, while the rebuttal gets blocked at the mail server? (Here's the snopes link for that on as well).

Folks, it seems as though your mail servers hate truth, so I'm asking and empowering you before you forward that next message about how clock hands have to be at 10:10 to mark JFK and Abraham Lincoln's death or how titanium rings can't be removed without amputation if your fingers swell need to do a little research to see if it's true or not. Truth is begging you.

(ps. Please keep sending the funny stuff.)
