Totally agree with all the comments here, seo broke google, and they don't care. Probably sells more adwords in the end.
I found uBlacklist from this thread, and the subscription functionality enables some collaborative effort.
So I've started making a list, but unfortunately there aren't many uBlacklist subscription lists out there yet.
Be interested to see how far this could go: https://github.com/rjaus/awesome-ublacklist/
