BBC Threats fail to faze
Once you stop paying your BBC licence they will start sending you computer generated letters which become increasingly strident and threatening. Examples are here.
I ignore these as I reckon I am keeping the local postie in work and I am not breaking the law. You do have the option of informing the BBC that you do not require a licence but they say they will still send out one of their snoopers to inspect your property. This is equivalent to my local supermarket searching my home on the off chance that I am a shoplifter. No way, Jose!
