Is it "bad" that I stole someone's photos and multiaccounted with them?

I did this when I was 17, on the site ExperienceProject. I used photos of a girl *and* a boy around the same age as me for two separate accounts. The girl appeared to be cultivating a modelling career at the time, and is quite successful now. She isn't particularly attractive though...to that extent I am not quite sure why I stole her photos in the first place. I soon deleted her account when it was discovered that I was indeed using "fake" photos. People assumed I was a male pervert in his 50's.
