SCP-049 is contained at all times within the bisks.net subdomain lattice, reachable exclusively through the fixed address https://crosstag.bisks.net/. As a Euclid-class object, personnel are advised that SCP-049'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-049 — designated "crosstag" in Foundation records — classified as a utility-class anomaly, is reachable at https://crosstag.bisks.net/.
Field notes recovered from the anomaly's own interface describe it thus:
type two Bluesky handles, get the entire history of them tagging each other — every reply where one @-ed the other, and every bare mention too, merged into one chronological timeline via searchPosts' author+mentions filters, both directions. @norvid-studies.bsky.social asked to see the whole back-and-forth of two accounts @-ing each other laid out as a scrolling list.
SCP-049 was brought to Foundation attention by @norvid-studies.bsky.social, who is credited in the containment log as the requesting party. First logged 2026-07-26.
Addendum 049-A: Euclid remains the Foundation's largest classification by volume. SCP-049 is unremarkable within that population and is not flagged for expedited review.
