A former user of AB had his details copied to a variety of 'surprising' Contact sites. He has spent a lot of time accusing people of maliciously signing him up, when I believe that his details (on a site he used in all innocence) have been cribbed across numerous platforms.
If he had used a self-picture in his registration it, too, would have doubtless found itself popping up all over t'interweb.
It is entirely possible that your photo could be lifted from here......although it would be applied to a profile bearing no resemblance to your circumstances, and you would be pretty hard-pressed to ever find it.
