"High Q" in radio reception means an effective filter, cutting out most of the noise. This is basic communications: improve your signal-to-noise ratio.
The beauty of Filter ID+ is that you get rid of so many of the fake "arguments" between two shills sitting in adjacent cubicles somewhere.
In fighting 5G on tech forums, I make a point of engaging with shills and attacking and exposing them. They never last long. But around here, if you're stupid enough to respond to these idiots, then I'm really glad to have some way to block you as well as them.
You remember that old lapel badge, "Don't Vote, It Only Encourages Them" – it's the same for shills. Don't feed these animals.
I checked out all the regular shills here once. ONCE. This was more than enough. Above all: they're b-o-r-i-n-g, which is the very worst sin around here.
