I don't mean for the title to be derogatory, but this is a rather frustrating problem, and I'm looking for a good workaround, given a language barrier involved.

I have a site set up for a plugin I wrote, and, rather than use the site's resources to write their own code, I've had people simply rip the code from the samples on the site. Normally, this wouldn't be any issue at all, but they are also taking my Google Analytics instantiation, so my Analytics data is getting very skewed by incorporating visitation data from their websites.

I've been able to contact the English-speaking site owners with little issue. The problem lies in the Japanese language sites that are yanking the code. I have no idea how to ask them to take down the analytics portion.

Long-term, I'm providing a package that streamlines the learning-to-use process, but in the meantime, what can I do about this language barrier? Is there a way around this problem that I haven't thought of?
