Behaviour for nonempty folders whose name contains a protected pattern, e.g. "Recycler"

[H2Swine]

I have protected the usual folder names, like "Recycler". That means that if I scan my music collection, which includes ZZ Top's "Recycler" album, it shows up in blue.

Since the folder is nonempty, it should not be displayed at all. Displaying it is actually even unwanted - then I have to check it manually to see that oh, I didn't accidentally (re)move the content.

I understand that for folders that lead to "unwanted" behaviour, like infinite loops I guess, then protection is a way to avoid it showing up altogether - that could make a cause for an ignore function that works like it does. But then in the very least, make it match exactly (wildcards supported) so that RECYCLER would be protected but ZZTopRecycler would not be.
