The controller allows for Application Filtering, where you can specify which apps to block or allow. However, the categories make no sense.

"PXrnXgraphy" (yes, I had to sensor this word in order to make this post....Just call it Adult like all other vendors do) only has one website:

Other Adult website are classified as Streaming:

Some categories are just empty and need some cleanup like "Moved", "Removed", etc.

As far as I can tell, it is also not possible to simply block "Streaming" as a category, meaning you would have to manually update the rules every time the App Database gets updated. (If it ever gets updated?)

This is a serious shortcoming to an otherwise incredibly useful feature.
