Techtide Marketing Conversion Flow Dark Pattern Review

Marketing Conversion Flow Dark-Pattern Review

Purpose

This skill reviews marketing conversion flow specifications - subscription sign-up, upsell interstitials, free-trial enrollment, and cancellation paths - for dark-pattern practices that invalidate consent or constitute unfair or deceptive acts under FTC Section 5, the FTC Negative Option Rule (ROSCA), the CPRA statutory dark-pattern definition (§ 1798.140(l)), and EU AI Act Article 5(1)(b). Dark patterns in conversion flows are a distinct and high-priority regulatory surface: pre-checked auto-renew boxes, asymmetric cancel vs. subscribe step counts, artificial countdown timers, and visually suppressed decline paths have drawn FTC enforcement, FTC rules with click-to-cancel mandates, and CPRA enforcement advisories. This skill works from a sanitized UX flow specification or annotated wireframe only. It does not review consent banners - that is the domain of techtide-marketing-consent-data-collection-review.

Lean operating rules

• Treat a free-trial or subscription enrollment flow that pre-checks "auto-renew at full price" (or any material recurring-charge term) as HIGH - pre-checked consent for a recurring financial commitment is prohibited under the FTC Negative Option Rule and invalidates consent under CPRA § 1798.140(l).
• Treat any cancellation path that requires more steps than the enrollment path, or that interposes save-offers between the cancel intent and the cancel confirmation without a direct-cancel alternative, as HIGH - the FTC Negative Option Rule and ROSCA require cancellation to be at least as easy as enrollment.
• Treat an artificial countdown timer applied to an offer with no real deadline as HIGH - it creates false urgency, a deceptive act under FTC Act Section 5.
• Treat visual suppression of the decline path (smaller font, lower contrast, grey-out, positioning below the fold, or absence of a visible "no thanks" option) as HIGH when paired with a visually dominant accept CTA - asymmetric visual weight subverts user autonomy under CPRA § 1798.140(l) and constitutes a deceptive format under FTC Section 5.
• Treat upsell interstitials that make the "continue without upgrade" option absent, invisible, or materially harder to reach than the upgrade CTA as HIGH - the absence of a clear decline path on a mandatory interstitial eliminates meaningful consent.
• Treat a subscription sign-up flow in which material price, renewal date, and cancellation method are not disclosed clearly and conspicuously before billing information is collected as HIGH - ROSCA requires pre-billing disclosure of all material terms.
• Flag "confirm-shaming" CTA copy (e.g. "No thanks, I don't want to save money") as MEDIUM - it applies social pressure but may not alone constitute an unfair act; combined with visual suppression it escalates.
• Flag any save-offer sequence on a cancellation path that does not offer a direct cancel option at each step as MEDIUM - save offers are permissible but must not be the only route.
• Flag countdown timers whose real deadline is authenticated by server state (session-scoped) as LOW - distinguish from artificial timers which are HIGH.
• Do not recommend removing a conversion step without naming the revenue or data-collection impact and an FTC-compliant alternative.
• Label every finding with evidence basis: flow specification provided, wireframe provided, documentation-based, or inference from missing element.
