The problem with this is illustrated in another comment where nixcraft's site, cyberciti.biz, was added to a personal block list. The content on the site does seem to be original and productive. I'd guess it was added based on the criteria of "I haven't heard of this site and the domain looks suspicious". I have a feeling that this will be true for other domains on this proposed master list. And the owners of those domains will have no recourse. Specifically blocking github clones seems doable. Adding anything else needs equally specific criteria or it will quickly become subjective and unfair.
