When I initially added the links [1] to the IETF RFC database (Internet Engineering Task Force/Request For Comments) [2] I made a typo. Instead of linking to “I-E-T-F dot O-R-G” I instead typed it as “I-E-F-T dot O-R-G [3]” and … wow. Easily a dozen redirects, probably half a dozen attempts to infect my computer and landing on some company website I never heard of hawking seminars to help you pass Cisco training and certificaitons [4].
Shudder.
