Right, I know that there must be a really simple answer to this, and that you'll probably be going "duh", but: is there any reason why you can't fake the referrer as being from a subdomain on your site, or even from a forum on your subdomain. Also, is there any reason why you wouldn't use a subdomain to carry out all you BH deeds (apart from risk) ? e.g. hat.com is my site black.hat.com is my BH site/subdomain forums.hat.com is my WH site/domain In this case, you would be sending people from black.hat.com to hat.com, but faking the referrer to look like the traffic was coming from forums.hat.com. Is this just too risky, and any other problems with this. Sorry for the stupid question EDIT: I suppose it could cause problems if google indexes the BH subdomain.
