Mazzy,
Same reason not all speeders are arrested. And not all shopkeepers/pubs that sell cigarettes/alcolhol to minors. And not all PPLs who accidentally stray into a bif of fluff at 2500ft. And not all white van men who block yellow box junctions. And not all cyclists who think traffic lights don't apply to them. (etc, etc, ad nauseum).
Enforcement is tricky. Although a gathering of "users" at, say, the local airport would be quite obvious, I suspect that nobody is really that interested. It's pretty harmless.
I simply wanted to make sure you were aware of the law. I use my scanner quite regularly to listen to traffic at Blackbushe. (And even to listen for friends coming to pick me up - I can be a Blackbushe before they land if I leave home when I hear their first radio call!
)
Cheers!
TPK
