I agree, but when the promoters (often at the behest of the artists), collude with primary ticket sellers, i.e. Ticketb*stard, See, AXS, etc. to offload large numbers of tickets to them, so can they in turn sell the same tickets on at a premium, then how to make it illegal? To compound matters the primary ticket sellers even set up or acquire secondary ticket selling companies like Seatwave and GETMEIN, what was previously seen as "illegal" becomes the accepted norm. In years gone by, remember how all concerts tickets were sold on this basis you were not permitted to sell them on and this drum was banged very hard and relentlessly by the primary ticket sellers?
I'm not speculating here about the promoters, I know this for a fact and it has gone on for a longggg time. The recent expose of the Robbie Williams ticket fiasco is just the latest and a highly visible turn of the wheel.
