I'll ask Rachel in the morning for the fraudulent SEO chap's name, company name and email address. I can see no good reason why I'd not be given that much information, given that she's said she's been tricked and embarrassed by him. And then I'll invite him back into the thread for a chat. After all, it's his thread.

If we get as far as asking him to return, I'll have a far better idea of why these shill advert threads keep happening to forums.
