that's going to happen ALOT, so your best bet is to put a watermark on your pix across the pic, not toward the side unfortunately, but slightly invisible but enough so that it can be seen. same with your vids. that's happened with alot of fetish models that i know, plus innocent ladies off ebay who sell their socks, nylons, and leggings. i know that's so sketchy. i had to do the same when i posted pix of my cars cause people would steal my identity from my plate number, and also say the car is theirs when there's my sister playing with the neighbor's dog in the background... i know, people suck unfortunately.
ps- thx for the address. everything came out great! only thing's i did not look at were when you were on the receiving end. i'm more (/f), other than that excellent job! she's awesome!
