Analysis of Terms of Service on Social Media Platforms: Consent Challenges and Assessment Metrics

Researchers Yong-Bin Kang and Anthony McCosker have published a significant study analyzing the Terms of Service (ToS) agreements of 13 major social media platforms. The core finding is that while platforms obtain user consent through these documents at account creation, they consistently fail to communicate consent-related information clearly. The study proposes a novel three-dimensional evaluation framework to assess ToS, focusing on Textual Accessibility (how easy the text is to read), Semantic Transparency (how clear the commitments are), and Interface Design (how the agreement is presented). This systematic approach reveals that ToS are not functioning as true informed consent instruments.

The analysis, combining computational and qualitative methods, uncovered critical shortcomings across all platforms. These include excessively high linguistic complexity, widespread use of vague and non-committal language, and limited disclosure about crucial data practices like retention and third-party sharing. Furthermore, the study found a complete absence of explicit interface-level commitments to granular or revocable consent. The researchers argue that ToS should be viewed as 'consent-bearing documents' whose design actively shapes—and often limits—user choice. The proposed framework provides a concrete method for regulators and platform designers to evaluate and improve consent mechanisms, moving toward more ethically robust systems for data-intensive digital services.
