Only to those who don't lose sleep at night over illegal radio operations.
There are people who lose sleep over stuff like that? Personally, I haven't really experienced all that much harmful "illegal" QRM (from stations running too much power or running dirty, freebanding etc..) to where I stress out at all, much less lose sleep.
Do I hear the splatter and mess when it happens? Absolutely, and quite often.. but it doesn't stress me out even slightly. For me it's just a hobby.. a hobby I enjoy and take seriously, but stress is reserved for things that really matter..
