Nothing like a little truth to squelch a rumor. I believe the article below analyzes very well why the scam was so believable to begin with and why it is so difficult to combat rumors of this nature. Bill 602P doesn't exist. Neither does the crusading law firm, or the Republican congressman, Tony Schnell, who is said to be pushing for an even higher email surcharge. It is all the creation of some unknown prankster with a fertile imagination and an understanding of cyberspace.
People are no more or less gullible than they have always been.
But now all these gullible people can send a message to other people. We have to be circumspect with every piece of information we get over this beast. Despite the Postal Services' best efforts to stamp it out, the rumor keeps springing back to life. That might not be so easy. The rumor is spreading faster than the facts can shoot it down.
