It's technically possible to fire up say 100,000 Azure VMs and have a script recognise the booking page and populate ref numbers and postcodes, but it would be fraught with risk.....what are See tickets doing to detect??...you can't test your scripts because you don't know the actual format of the booking page...also what payment method do you use? If all the same card it would be spotted, if different cards then people would have to hand over all their details. Large up front cost of setting up system with a high probability of failure. Easier to just rope in 100 humans, particularly on the first sale where you don't immediately pay.
