Containment of SCP-133 is passive: the anomaly is bounded by its own hostname and does not propagate beyond https://moottris.bisks.net/ under any observed condition. As a Euclid-class object, personnel are advised that SCP-133'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-133, catalogued internally as "moottris," classified as a recreational-hazard anomaly, is reachable at https://moottris.bisks.net/.
Field notes recovered from the anomaly's own interface describe it thus:
Tetris, played with your social graph. type a handle and every falling piece is one of your moots: its shape comes from the zodiac sign of their account's birthday (routed through the seven classical planetary rulers, one per tetromino), its fall speed from how many posts they've made in the last 48 hours. clear four lines at once and Mercury goes retrograde — controls reverse and the sky does something about it. @isolyth.dev asked for tetris where block shape comes from moots' star signs and speed from their post frequency, with something crazy on a four-line clear.
SCP-133 entered Foundation custody after being flagged by field asset @isolyth.dev, whose transmission initiated standard containment procedure. First logged 2026-07-26.
Addendum 133-A: Euclid remains the Foundation's largest classification by volume. SCP-133 is unremarkable within that population and is not flagged for expedited review.
