Continues to send spam emails despite requests to stop. Appears to be a pyramid scheme.
Updated 5/25/2012: Changed from "Spam" to "Ethical issues." Primary site may not be a spammer. Spammers do seem to be tolerated in that they operate from subdomains of the main site, despite alleged TOS that allegedly do not permit spam.
Also, this site is part of a network of sites whose purpose seems rather murky. Specific details about what services they offer are unobtainable without joining via Facebook. Caveat emptor.
