Just because you can hack another app doesn't mean you should. You're just enabling another form of spam. There are more interesting things you can work on. Don't be that guy.
Just having some fun. One of our out of state interns was playing on tinder (doesn't really know anyone around here) after a long day of work and we thought it might be fun to see if we could automate the process. No harm intended; just blowing off steam.
For what its worth, I think its a funny/cool project that you guys were obviously just messing around with. A lot of these top comments are taking this much to seriously. Cool execution guys!
It was also a bit of a teaching moment. I was trying to show our intern how to use http://www.cycript.org/ for fun at night and he happened to have the Tinder app open. We love hacking things.
