This is quite a massive blow to many mainstream webmasters who use BMR's massive network of blogs for "guest blog post" in-content linking.

There are still quite a few other providers out there but Google's been on a tear lately...
The alternative is to do it the old school way-guest blog posts (contact with offer, get a tentative okay, write the piece, get approved, move on to the next one). Slow but might provide a better fit.
