Somewhat as a companion piece: An... experimental bot I wasn't able to push out in time:
@fuckeduprefs_bot@infosec.exchange . I have no idea if it actually works but I kinda need to test this in prod so... well, at least it's posting Unlisted

It checks for new references* since the last run and then checks for various issues:
malformed URLs (to a degree, unfortunately what qualifies as a well-formed URL is quite ... permissive)DNS-level unavailabilityHTTP-level unavailabilityHTTP 5xx statuses
While the bot respects robots.txt checking for 404 isn't feasible, given the tendency of some providers to still 404 bots they allow under their robots.txt (
#fuckCloudflare ).
The bot almost certainly also has stability issues & will almost certainly produce FPs & I am not even sure it will "catch" anything ever. So, uh, not sure it's worth to follow rn

New blogpost: A little detour from the CVE linkrot: What if we just made up the references in the first place?
https://blagh.nyanbinary.de/posts/look-ma-im-a-cve-reference/
Tldr: For about 3 years a portion (<10% or so) of MITRE CVE records contained references of ... beyond questionably quality, including multiple hundred completely bogus domains.
