Is there a way to block all of the gaming schlock on the Roku Channel?

We blocked a bunch of content creators and eventually just removed YouTube, but the Roku channel has all of this content of grown men just acting like morons over games. They're not even playing half the time.  I have loved the Roku products since the early days back when they came in a black project box, but now that I have a kid if there's not a way to fix this, I feel like we may be about to part ways.
