Google /General blacklisted or banned sites - Any list ? ( even of worst offenders )

[bmnobbs]

Has anyone come across any sites/blogs that list the worst banned or blacklisted sites, or, better still, has a definitive list that's updated as new ones get blacked ?
Are there any Free Directories that anyone knows of that are banned/blacklisted ?
Thanks
