Happened to me too, but not on GS, though I dont know for sure.
Anyway, I look different in person than in my pics, woo hoo. So it isnt a big deal to me, and I only send pics to girls I feel I can really trust, not girls I have known only for a short-time. But even then, if they saw me in person they will not recognize me based on the pic. hehe.
This is really sad.
Dont trust even girls on net. You cant KNOW they are girls. Lot of men disguise as girls to become friend with sudden girls, its a sick world. Some girls poose as men, so they dont have to bother getting pms etc.
I never ask for pics neither do I give mine out.
Better to be safe than sorry. Learned it the hard way....lol
