I’m skeptical that casino will use this kind of tool since it’s very hard to extract data from social media entry manually and insert it to the tool.
It's a great tool and am speaking from experience though manual entries for a large sample size could get tiring pretty quickly which is why the casino could speak to Bitmover for some sort of automatic entry script and pay him for his work.
I believe some managers of companies have announcement threads in Bitcointalk as well as host their campaigns, contests here will do see your tool is very helpful for their jobs. Hopefully you will receive donation from them as well.
I have used it regularly with my alt-account and I can confidently say that it's an extremely useful tool as long as the sample size is small.
