 Q) How would you detect users who manipulate photos rating by creating fake accounts?
 Couple of ways to detect same users:
 - drop a unique cookie on the user system which will help determine if different users came from the same computer. A post processing service can be setup to check different users from same computer.
 - limit the number of ratings that an IP or a user can perform in set period of time
 - to avoid automatic bot based rating, have the rating button to be a randomly lazy enabled.

 Q) What would you change on 500px.com and why?
 An image is worth nothing if it cannot be discovered. 500px thou serving top quality images has a very minimal search capability. Image discovery is probably the most important feature that I would recommend for 500px. Image discovery features such as:
 - search image by dominany color
 - search image by number of faces (face detection, gender detection, age estimation etc)
 - categorize image as editorial, creative etc
