DeGenTWeb: A First Look at LLM-dominant Websites

This batch of arXiv items spans networked-systems, ML/LLM infrastructure, and privacy/control mechanisms. Key contributions: DeGenTWeb — systematic method to identify LLM-dominant websites, showing high and growing prevalence in Common Crawl and Bing and noting that off-the-shelf LLM detectors underperform in realistic web settings; Network Digital Untwinning — mechanisms (single and parallel) for targeted removal of contributions from network digital twins with rollback+noise and remapping and provable indistinguishability; RouteProfile — a structured design space for LLM profiles that shows
