Dark Patterns is a list of deliberately user-hostile web site design patterns typically intended to deceive or exploit unwary users. These range from the trivial and clumsy (interfaces designed to impair price comparisons) to slyer tricks such as sneaking add-ons into shopping baskets, making specific options deliberately hard to find and spamming all your friends, typically after getting permission on a false pretext. Among the offenders listed are the likes of Ryanair, CreditExpert, various travel and electronics shopping sites, and, of course, Facebook, which has its very own pattern.
