Standard containment for SCP-152 consists of restricting the anomaly's route to https://postwith.bisks.net/ and monitoring for route drift. As a Safe-class object, SCP-152 may be accessed by any individual possessing a standard web browser and an internet connection; no special clearance is required for observation.
SCP-152, referred to by Foundation staff by its working name "postwith," classified as a utility-class anomaly, is reachable at https://postwith.bisks.net/.
The clearest surviving account of the anomaly's function is its own front-page copy, reproduced below:
an atproto matchmaker, Lunchclub-style but peer-to-peer: post a topic and a goal (mentoring, gaming, foodie, code, ...), get auto-matched with everyone else on the same topic, propose a meeting, they accept or decline, either side logs how it went. every record — profile, proposal, response, feedback — is written straight to your own PDS; a Durable Object just watches the firehose to build the live match index. @antiali.as asked for a matchmaker; "execute flawlessly" kept it going.
Foundation awareness of SCP-152 began with a tagged mention from the individual on record as @antiali.as. First logged 2026-07-29.
Addendum 152-A: Personnel are reminded that Safe classification describes containment difficulty, not triviality. Do not treat SCP-152 as uninteresting on this basis alone.
