It's the photo that keeps on giving;    

It would be piss-easy for a bot to manage, though.

I've heard that ticket sales for other events that use the same system have included the question 'are you still there?' on each window/browser you have with a place in the queue. If you don't confirm you are, it'll assume you're not and that place will drop.   I've no idea if Glasto/See will adopt this, but it would be challenging to keep on top of with many windows open.

People who're struggling are already priced out, so I don't think a bump in price will affect who attends. There'll still be a cross section, leaning young. I also think they'll do a soft breaking of the £400 ceiling, keeping the ticket price just below but having postage take it over. Next year the ticket itself will be over that threshold.
