Dark Pattern
Dark patterns are user interface design choices that benefit an online service by coercing, steering, or deceiving users into making unintended and potentially harmful decisions. We conducted a large-scale study, analyzing ~53K product pages from ~11K shopping websites to characterize and quantify the prevalence of dark patterns.
Language, dark/black = bad
This might not be obvious, so I'm gonna say it, maybe some can benefit from that thought:
Using a language, where "dark" or "black" is associated with "bad" might no be a good idea.
(I don't want to argue on it. I don't have a better term. Don't @ me).
