Todd;
I've coined a word for this behavior. These guys should be called PodScum, and they are guilty of PodScumming. (like pond scum only worse)
I recall recently emailing you about some of these guys. I was poking around on Blubrry looking for podcasts on specific topics. I thought I had found some interesting ones (Home Hidden Camera and High Blood Pressure Treatment & Medication Reviews), only to discover that they were fronts for advertising sites.
You are 100% correct to ban them. To allow such "empty" content to continue would only give your network a bad name over time, and it causes credibility issues for podcasting in general. Imagine a person new to podcasting looking for content that is of interest. How long would they excited about this new media if all they found were such sites?
Consider adding a button on each podcast that allows folks who stumble on something like this to flag it as 'empty' content? Your team would review all flags and ban accordingly.
