Some of my bugbears in no particular order: "Locked Slingshot" in Facebook's slingshot app [1] is an interesting one. Not the worst dark pattern in the world, but quite manipulative nonetheless. Forced continuity services where they make a recurring membership look like a one-off purchase. Justfab [2] is still at it. Arguably they’re playing this card more than ever right now. The way payday loan companies like Wonga [3] represent compound interest to target customers. They only present a a “best case scenario”, using sliders to imply a control, when in fact there no modelling of missed payments and true APR is hidden. The relentless series of pre-checkout upsell pages you get with most domain name registrars (e.g. godaddy) and low cost airlines. Abuse of html controls to make them behave in unexpected ways, e.g. Airasia [4]. Requiring cancellation of an online service by phone, and making you give reasons / listen to a long script / jump through hoops before allowing you to cancel (e.g. The Times of London). 1. http://www.pocket-lint.com/news/129454-hands-on-slingshot-app-by-facebook-for-iphone-review http://www.pocket-lint.com/news/129454-hands-on-slingshot-ap... 2. http://www.justfab.com/ http://www.justfab.com/ 3. https://www.wonga.com/ https://www.wonga.com/ 4. http://usabilityhell.com/post/74591297913/airasia-com-bad-usability-by-design-to-steal-your http://usabilityhell.com/post/74591297913/airasia-com-bad-us...
