iTunes is sending me a podcast I didn't subscribe to

I was surprised to find a podcast from openpodcast.org (Lesley Belle Promo - OpenPodcast.org #2824) on my iTunes this morning. They don't have me listed as a subscriber. I do subscribe to openpodcast but I use Doppler to pull it in and iTunes is only the player. That sub is in it's normal place but for some reason I have an unsolicited download as well. It's located in the iTunes Podcast section not as a single playlist like the other Doppler catches. Most peculiar.
