Obtain screenshots of the offending domain name or website, including all fraudulent uses of your pages, names, logos, graphics, text, images, and other data. This should be done as quickly as possible. Record any information that you can find concerning who may be running the fraudulent website or who may have registered the fraudulent domain name.
The screenshots should be carefully preserved in both physical and electronic forms so that they may be used as evidence in a court or in a dispute resolution procedure.
It is likely that someone who can commit a sophisticated website fraud can also identify who is visiting their site. You may want to consider using a masked computer that allows you to access the fraudulent website without leaving evidence of your visit. Quick and efficient use of a masked computer means you can gather evidence of the fraud before those involved have the chance to shut down their site.
