>Partway through this article, Winbuzzer asks me to "Install Winbuzzer Prompt Station." I don't think this is a legitimate source.

It's just a first-party ad. There's even a "PROMO" tag above. The fact that it's first party, combined with the fact the site isn't too popular is probably why it didn't get blocked by your adblocker. But it doesn't make the site less of a "legitimate source" than say, The New York Times, which also has ads.
