Coopting quality sites is a bit of a cottage industry. There is also a significant amount of hacked wordpress sites. Their domain may be quite reputable, but they're unknowingly host to a ton of spam.

It's a bit funny because the authors of the paper suggest this modification and explicitly states it makes the algorithm extremely resilient to manipulation from commercial interests.
Unless you have some pretty evil supervillain scheme, no moral compass, and succeed.... that world is never coming back.
