Mass email forwards can quickly cross the line from amusing distraction to unwanted annoyance. If you care deeply about stopping someone you know from sending borderline -spam, you might be bold enough to try stopforwarding.com. The website sends a curt, anonymous email informing the person that a friend has requested that they stop sending forwards.
"Please do not forward chain letters, urban legends, potentially offensive jokes, videos or photos without being asked or first receiving permission," the email continues. "If you find something that you want to pass on and you genuinely think the recipient will enjoy it then forward it to that person only (not in an email blast to all your friends and family) and include a personal note about why you enjoyed it and why you think they will too."
