That's mostly because you ignored the examples given - with an IPv4 /28,
when writing ".232/28", would that mean "I want to really block the 
subnet starting at .224, ending at .239?" or "I did the math incorrectly
and want to block ".232-.248" (which cannot be expressed by a /28).

This is why I agree that a warning can be useful, or making it explicit
how things are evaluated ("x.x.x.232/28 parsed as x.x.x.224/28").

I also agree that the behaviour of "just not matching things if such a
config is given" is the worst choice :-)
