I thought this might be an interesting topic you might like. At least I hope so anyway. Just today I came across a fake Facebook profile using your photos. This is the profile's link: http://www.facebook.com/profile.php?id=100002527860194
yeah i´ve seen a few :/just to be clear guys. i have no accounts on any of those sites. we´ve been thinking about becoming modern and start using some of those social websites :p but right now, if you see "me" on facebook, twitter, myspace, tumblr, etc... its not me.
You should go on them then. A lot of others promote their sites too on them. That one I showed above didn't say it was you though, but they were using your photos.
