One of the most annoying types of spam are chain letters. There are several sites dedicated to stamping out urban legends, hoaxes, and rumors. BreakTheChain.org wants to be your online source for chain letter evaluation. Other sites are old and outdated or thorough but unsearchable.
BreakTheChain.org takes itself very seriously, even allowing you to sign up to receive its twice-monthly bulletins. It’s even got some real recent ones.
To my mind, the site’s true power is the search engine, which allows you to put in a choice phrase and find matches. You can quickly discern if what you’re reading is completely bogus or just needs more investigation. If you’re not sure, you can submit one for consideration.
