city sex.com review: unsolicited spam lewdity 1

I am persistently getting spam from members the above site. They contain photos of a girl (sometimes with nudity), and have typical return addresses such as Lara Falcon [[protected]@lara-falcon.info] or a site link like http://www.lara-falcon.info/. There is no way to contact anyone via the site either. Here is copy of header information, etc :
