Since I am a lazy asshole I went to copy my post in Political Podcasts to a friend who asked about the same topic, and I've discovered that all the IHeart Radio links have part of it censored (Worst Year Ever for example). I assume that since the censored part consisted of r, t and .com which is an address of a Russian propaganda site it was hit by some sort of a filter. Not sure if it can be adjusted to be less aggressive and for example only nuke the address when there is "." or "/" before it, or if there are other addresses banned that are so simple that they risk messing up legitimate stuff, but it may be worth checking.
