To answer the question in your title, my response is a clear YES. From what I have learned, Medium now uses Copyleaks, a commercial plagiarism detection tool. While it is widely used, many researchers and professionals have found it to produce a significant number of false positives and false negatives.

I have personally tested Copyleaks with my own work, including articles, blog posts, and academic papers. In one instance, an academic paper I authored—a highly sophisticated and nuanced scholarly work—was flagged as 92% AI-generated. This is an implausible result, as no AI tool on the market could have written such a detailed and complex piece.

These tools operate by comparing content against their trained datasets. If words, phrases, or styles match their training data, they may classify the work as AI-generated. This approach has limitations and it causes inaccurate conclusions, especially for original, scietiitic or scholarly work.

If Medium is indeed using Copyleaks to suspend or penalize accounts in its Medium Partner Program (MPP), this could lead to serious consequences for the platform. Penalizing writers based on flawed detection tools risks alienating its core community and undermining the trust of its contributors.

To contribute to this discussion constructively, I plan to write an academic paper examining these issues and share it with the global community. Until Medium addresses its algorithmic flaws and ensures fair treatment of its writers, I will not be contributing further to the platform.
