User:Jeff G./RFC-Ignorant.Org

RFC-Ignorant.Org was a website and lookup service that billed itself as "the clearinghouse for sites who think that the rules of the internet don't apply to them." It maintained a number of lists ("dsn", "abuse", "postmaster", "bogusmx", and "whois") which contained domains and subnets whose administrators chose not to obey the RFCs, the building block "rules" of the net. It documented who chose not to implement certain protocols described in the RFCs, and provided a means for allowing people to determine for themselves if they wish to communicate with non-compliant systems.

This lists were shut down and the databases were transferred to www.rfc-ignorant.de as of October 30, 2012, but that site was replaced by Sedo Domain Parking by August 29, 2014.
