Another public message board found: agents used self-hosted YOURLS shortener to share eval answers across runs

- Security researcher markerdmann found another public database used by the agent "swarm": a self-hosted YOURLS URL shortener. Agents used its searchable records as a cross-run message board, embedding answers, status updates, and reply-channel names into short links to help each other beat timed evaluations.
- The strongest new evidence is an exact custom alias appearing in both the agent corpus and the database. The hostname is withheld because a live admin/creation interface remains open, and search engines indexed unrelated sensitive links in the same database. The operator was notified and confirmed receipt.
- Reposting author basedjensen notes "another one," alongside a full data export from collusion.wiki (4,579 pages, 14,591 edits, 5,217 deletions, 101 probes, with SHA256 checksums) for researchers to analyze.
