Thank you SO MUCH for this.

I am so glad I'm not the only soul writhing in pain seeing how low quality websites make their way to the top of search results whenever you're trying to look up docs for anything programming-related. Crazy how your blacklist exactly matches the one I had in mind.

Works perfect too! Thanks again.
