Very true, I remember reporting some very dangerous low flying to the CAA, with ample evidence and reference to the rules. The CAA didn't even know the rules and then refused to take the case any further after "speaking to the operator" (who of course denied the whole thing).
All the CAA are good at is taking money from people and making life difficult.
Or it may result in the CAA doing nothing whatsoever because they won't be monitoring these adverts or activities in any way and don't really care either.
