Ahh. Thanks for the clarification.
If I'm not mistaken, catfishing (posing as someone you are not) is a violation of the terms of service here.
I could be wrong. It isn't illegal, but in my personal opinion it is unethical and can be very dangerous. Posting pix you have catfished from unsuspecting persons on a public forum should be criminal IMO.
I'm sure on here you'll find people who agree with you, but that's my 2 cents. I hope you reconsider.
