Manipulation
Hard to Cancel
A cancellation flow deliberately buried behind multiple menus, forcing the user to hunt for an exit that should be one click away.
Manipulation
Hidden Subscription
A recurring charge enabled by a pre-checked box in small, low-contrast text on what looks like a one-time purchase.
Manipulation
Hidden Costs
Extra service, processing, or handling fees that appear only at the final checkout step, inflating the price shown earlier.
Manipulation
Sneaking
An extra item quietly added to the cart without the shopper's request, relying on them not noticing before paying.
Manipulation
Trick Wording
Confusing double-negative phrasing designed to make it unclear whether checking a box opts you in or out of something.
Manipulation
Preselection
Data-sharing or marketing toggles switched on by default, requiring the user to notice and manually opt out.
Manipulation
Fake Urgency
A countdown timer implying a deal is about to expire, which actually resets every time the page reloads.
Manipulation
Fake Scarcity
“Only 1 left” or fabricated live-viewer counts that regenerate randomly rather than reflecting real inventory or traffic.
Manipulation
Disguised Ads
A paid advertisement styled almost identically to organic content, with only a tiny, easy-to-miss “Ad” label.
Manipulation
Comparison Prevention
Pricing plans deliberately structured with different units, billing periods, and included features so no two plans can be compared on the same basis.
