Having been fighting copyright violators for 20 yrs with my artwork & photography, I'll contribute a few things I've learned. First, if you do NOT enforce your copyright, it would then, by law, set a precedence that you DO allow people to violate your copyright. (ie: Your “copyright” is meaningless) If you're going to ALLOW your images to be horked off the internet, then don't put the copyright stamp on them. MHO is that it has nothing to do with appeasing them or being the *nice guy*.. it has everything to do with setting a precedence re obeying the copyright laws.
Besides, at WHAT AGE is this gal (or her parents) going to learn that copyright violation is a crime? .. If YOU diminish this violation, then why should she give it or YOU any credibility?
For an example of notification: I have a boilerplate letter that is too long to post here.. but in essence, though you can let them know that you're flattered they enjoy your work, they are in direct violation of the copyright laws protecting your images on the internet.. (go do some reading http://www.uspto.gov/#
) They need to “cease displaying, reproducing or distributing any unauthorized copies of your copyrighted work. “
"Under the Copyright Act, (you) are entitled to an injunction against further acts of infringement, recovery of damages and/or recovery of use fees attributable to the infringement of all infringing copies. Even without evidence of profits, the court may award statutory damages up to $100,000 plus the costs and attorneys' fees incurred in bringing suit. See 17 U.S.C. 502 - 505."
.. then say something about .. “we hope it won't be necessary to invoke any of these remedies.. but we need a written confirmation that this (cease & desist) has been done.” within seven days of your receipt of this letter. If the recipient is a minor, then the letter needs to be sent to the parents.
It will require a decision by you weather you're shooting for fun and giving your photos away... or if you intend to step up to the plate and defend your copyrighted images. But PLEASE, for the rest of us who DO enforce the copyright laws, please do not illustrate and teach others that the copyright laws don’t matter.
