Containment of SCP-189 is passive: the anomaly is bounded by its own hostname and does not propagate beyond https://steamtags.bisks.net/ under any observed condition. As a Euclid-class object, personnel are advised that SCP-189's behavior is only partially predictable under repeat interaction; researchers should log anomalous outputs to the site's own Addendum before treating them as expected behavior.
SCP-189 — designated "steamtags" in Foundation records — classified as a utility-class anomaly, is reachable at https://steamtags.bisks.net/.
The clearest surviving account of the anomaly's function is its own front-page copy, reproduced below:
pick any Steam game and see its community tag cloud, sized by vote count — then rate for yourself how well each tag actually fits, 1 to 10. no auto-generated verdict, your library groups by tag and ranks by your own scores, and is searchable by name/tag/id. works anonymously in localStorage, or sign in with Bluesky to sync it to your own PDS as <code>net.bisks.steamtags.rating</code>. also does Steam OpenID login to verify who you really are. @7778777.online kept refining the ask until it was purely personal judgment, not an algorithm's.
SCP-189 was brought to Foundation attention by @7778777.online, who is credited in the containment log as the requesting party. First logged 2026-07-31.
Addendum 189-A: Euclid remains the Foundation's largest classification by volume. SCP-189 is unremarkable within that population and is not flagged for expedited review.
