Keep in mind: Preprint posted on arXiv on 2026-09-02; Jack Neff reports it as published by the ACM. The crawler logs into no site and has no browsing history, so no EID on its visits belongs to a real person. Data runs from January 2022 to May 2025. Two authors work at ad tech research firms Adalytics and DeepSee.io.
