Content theft is easy to prove – just go to the wayback machine and see who had it first.
Then go and complain to google, including the evidence. Google will lead you through the legal steps to file.
Then go back to your am, and if up to then s/he was not cooperative, they will be when presented with this.
Also go to the host of the copycat and submit your evidence and the copycat’s account will usually be closed.
I have had 100% sucess handling it that way. The copycat gets removed from google, from the aff program and loses their hosting/server.
It doesn’t pay to copy!
