There's a huge number of replicated Chinese spam sites (xyz123.com, xyz456.com, mob123.com) that link to my site. I don't know why or when they started linking to my site, but I know that i didn't have anything to do with it. Your position seems to be that it's legitimate that I'm penalized for this. It's hard not to take this issue personally. It's like being falsely accused of a crime and having to pay a fine.
