Sometime ago a man made a better version of the Odeon's (a UK cinema chain) website. His version was accessible but also mu h easier to use. People could use his site to buy tickets from Odeon. They shut it down and stuck with their terrible site. I'm on mobile and finding links is frustrating, but here are a few.

He did some other sites too and as far as I know they all got taken down pretty quickly.
It's interesting to see some history of web scraping and how much people protect their, well, i don't know what is being protected there.
