That's an ambitious goal, I'm not sure to see how that would be maintainable on the long run. On a much smaller scale, if anyone is interested, I maintain a black list focused on those code snippet content farms that gets in the way when you're searching for some error message or particular function here https://github.com/jhchabran/code-search-blacklist .
May I know why my domain (cyberciti.biz) was added to that list? I created my site back in 2000, and there was no StackOverflow or anything. So much for creating original content and then getting labelled as a spammer. In fact, some of the top answers on StackOverflow were copied from my work without giving any credit to me. Some people do give credit tho. But, go ahead block a site that actual humans maintain over 2…
Glad you said something though, I wouldn't have looked at it twice without a human attestation.
