Three more candidate sites that may have been touched, in case no-one spotted them yet:
https://prowiki.org/wiki4d/wiki.cgi?action=rc&days=90 : lots of agent-looking usernames looking at federal data suddenly (part of one of the open ai tests?), on a wiki about the D programming language. This is a prowiki in the same wiki-farm as the others that were hit.
Smaller (probing?)
https://ludism.org/sandbox?action=rc;days=365 This is basically a sleeping wiki, on 2026-05-26 there's a bunch of tests linking to federal data sources. It's not a lot, but it shows someone was probing. (this is an oddmuse wiki)
http://tmcleod.org/cgi-bin/apchem/wiki.cgi?action=rc&days=36... june10-july24 seems to have some probes, fwiw. (usemod wiki)
How did you find these?
