One of the first superstitions of the digital era was the chain letter. An immigrant from the postal service, the superstition came in the form of a letter, and later an e-mail, threatening you to copy the message and send it to several friends. Why you'd do that to a friend has always been a course of mystery, stretching back to the first girl to ever compose a chain e-mail. To be fair, she was dead when she did it.
Anyone who follows the instructions of a chain e-mail is passed over and experiences none of Google's first paranormal agent. Anyone who disregards such an e-mail, though, will be haunted by the ghost of the girl who set the scheme up. She will haunt your inbox for the rest of your life, complimenting your good taste by acting as a secondary spam filter. You will very likely never see another penis enlargement ad that she thinks you don't need.
Skeptics should still be wary, for though disregarding her power has benefits, calling her work a superstition is hazardous. Doing so upsets her ghost and cause her to expose your search history to a loved one. That has never ended well, and ironically, its contents are always passed on by word of mouth.
