How do Free lottery websites generate enough $$?

Hello,



Their is a website called free lottery postcode and it gives away $500 a day and the money raised it all generated from adsense...



How much would the cpm be meaning the traffic is not targeted?



If someone has knowledge in this can you explain how it's done?



Apprarently it has around 200-300k visitors a day..













Please help.

Thanks!
