When I visit this site I get a spurious message warning me I have viruses on my PC and I will be reported to my ISP unless I do something about it.

If someone does not know this is a scam they will end up out of pocket completely unnecessarily.

I cannot find a moderator to contact! Surely someone is responsible for this site!

Those are private messages from a spammer. We did take measures to prevent that, but if you haven't been here in a while, you may have a message that was sent a few months ago. We're pretty sure there aren't any new ones being sent.
