A couple things about the Tinder App...

What is the technology hackers use to post bots on Tinder?
Is it php? Is it an app thing? Is it some sort of a cron job?

Also is it something they use with Tinder's agreement? Maybe Tinder makes money with it? Because this is not developed from within Tinder, how can they run it and make 10,000 right swipes a day?
