Is it illegal to create FAKE dating profile?

My friends and I have done it before and never got in trouble. However, today we had a sleepover, and we decided to make an account in like 2 years on OKCupid. We do it just to see the entertaining responses from all the weird guys on their looking at the pretty girl on the profile pic- she's a Romanian young model (television personality, and singer) and it looks like she is an actual person. So someone decided to "FLAG" the pics, as he sent me a message saying he did, and OKCupid deleted the profile pic. Now I put the profile pic back on, could I get in trouble for it? I usually delete the accounts when I get bored. lol. I don't take it too for or anything. I don't even flirt. lol. I'm 16 by the way.
