Dark Pattern

A user interface design deliberately crafted to trick, manipulate, or coerce users into making unintended choices that benefit the service provider rather than the user. Dark patterns include hidden costs, forced continuity, disguised ads, confirm-shaming, and misdirection. In accessibility contexts, dark patterns can be especially harmful as they may be harder to detect through assistive technologies — for example, a screen reader user may not recognize that a visually prominent "accept" button is designed to trick them into a subscription, or that a dismissal option is deliberately hidden.
