Infinite Scrolling

Infinite Scrolling is an interaction pattern formally classified under “Engagement Traps” and “Interface Interference.” While initially designed for seamless mobile consumption, it functions as a dark pattern when it deliberately removes a user's navigational agency and natural stopping cues. By automatically appending new content to the Document Object Model (DOM) as the user approaches the bottom of the viewport, it forces continuous consumption. Furthermore, it often acts as a structural trap by perpetually displacing terminal navigational elements, such as the website's footer containing critical privacy or contact information, rendering them physically unreachable through standard interaction.

Condition 1: Autonomous Content Injection

Y_{document_end} - Y_{viewport} \leq τ_{trigger} ⟹ E_{fetch} () = True

Given

To identify the removal of explicit user choice, we define

Y_{viewport}

as the bottom vertical coordinate of the user's current screen and

Y_{document_end}

as the absolute vertical coordinate of the content container's end. We establish

τ_{trigger}

as a predefined spatial threshold (e.g.,

800 px

before the end of the document). The feature triggers if the interface algorithmically forces the continuation of content via an asynchronous event

E_{fetch}

without requiring an affirmative user action, such as a “Load More” button, whenever the viewport crosses the spatial threshold:

Condition 2: The Unreachable Footer

v_{scroll} > 0 ⟹ \frac{d}{d t} Pos_{y} (N_{footer}, t) \geq v_{scroll}

Given

A fundamental deceptive tactic involves the literal evasion of utility links. We define

N_{footer}

as the semantic <footer> node and

Pos_{y} (N_{footer}, t)

as its absolute vertical Y-coordinate at time

t

. By calculating the distance

d

between the viewport and the footer relative to the user's scroll velocity

v_{scroll}

, the algorithm detects kinetic displacement. The feature triggers if the system continuously mutates the DOM to push the terminal node further down the Y-axis at a rate equal to or faster than the user's scroll velocity, effectively preventing any physical interaction with terminal information:

Condition 3: Semantic Attenuation of Content Boundaries

\neg\exists n \in N_{feed} : Match (T (n), Pattern_{boundary}) = True

Given

To establish a semantic baseline for Infinite Scrolling, the algorithm detects the absence of pagination or content-termination language—“page 1 of N,” “end of results,” “no more items.” The feature triggers if a scrollable content feed lacks any semantic boundary marker within the rendered text, indicating that the interface deliberately removes linguistic cues of completion to encourage endless consumption:
