We initially used infosec.exchange and we created this up after infosec.exchange started being defederated due to CISA making an account. CISA is the US federal agency for cybersecurity infrastructure security, and definitely not law enforcement as it was portrayed. Even if they were law enforcement, I still would have found defederating the instance because of a completely non-toxic, innocuous account to be ridiculous. This plays into why we didn't import a list.
