Yes 100% agree about this.
I never know, as I hear stories of people having zero issues, they filled out the form, perhaps get 1 letter a year, and that was that.
Other people have a ton of grief.
Mind you, some people do bring trouble onto themselves as they refuse to fill out any form to tell the BBC they don't watch it, and just seem to take joy in all the trouble and posting on Youtube.
I will admit, I'm still unsure about what path to take.
If they come round to check, just be difficult and say, can't come in and ignore them (which whilst totally within your right, it kinda just feels like you have something you are hiding and don't want them see)
Or let them in, offer them a tea/coffee, be super friendly, explain you don't watch Live TV, show them you took down your TV antenna's and have no arial leads where your TV is.
Logically being friendly, open, and showing them nothing to see here, feels like they would go away and leave you in peace as opposed to looking guilty by shutting the door in their face.
But perhaps I'm just a naive idiot on this one.
