Is it immoral to make a fake profile on POF?

Is it immoral to make a fake online dating profile at POF with a random pic? Is it illegal?

I made a profile in a different city of mine with a fake pic (rated the same “hotness” as me on hot or not so I can test the game, not the looks). I just want to figure out the system so to speak since I never did the online thing. What profiles get what responses. What emails to send. etc.

I have no other way of testing these things or else I would?

Random question: Is 7/15 response rate, 4\15 conversation rate, 3\15 number\AIM rate good?
