nude NO, full body 3/4 yes, there in not a lot of damage someone can do with a full length photo taken from half way between face on and to one side, nude would require a lot of trust as would a "passport" type photo, I'm not going to say be careful because I know you are.
I wouldn't trust them. Showing your own picture isn't sharing your own trust.
If I were going to trust them then I'd have them do a test of recognition.
DNA test, Driver License, all that stuff. So I know that they are saying the truth about how they are recognized, or more simply, who they say they are.
Actually believe it or not, I'm 14! I'm the school's bookworm! Mega bookworm. lol
I have photos of myself here. I have nothing to hide. But I'm much older than you are, you should be very careful.
After doing a google image share to make sure it's legit, yeah.
no. i give my picture, i give away other things too...no need for that
