How do I (successfully) Mute an Entire SDMB Category

I tested just now.

I muted MPSIMS and all threads disappeared from the Latest list except for threads I had set to Tracking. So GoGo On Vacation! -A Holiday MMP disappear but Russia invades Ukraine {2022-02-24} (Part 2) remained when I clicked Latest.

So did most Cafe threads disappear with just those set to tracking or Watching left?

It makes sense that it works that way.
