Hi hheenry and welcome [webmasterworld.com] to WebmasterWorld!
Is this just one person or have you found several people doing it?
Sounds like a case of fraud.
Are they pretending to be acting on your behalf? In some cases yes
sounds like it might be a case of libel.
they claim that the content on my site is a copyright infringement
IANAL, but you should consider contacting one to see if you have a case. Most likely, unless you can prove actual damages cause by the person's actions, you don't have a case. However, a cease and desist letter from a lawyer may make the issue go away once the person knows he's on your radar.
