Well htaccess should cover the hotlinking aspect, and the page just sitting there doesnt bother me as the sponsor links havent been changed...
But what appears to be happening is that his url (of MY page) gets returned in search results, the surfer clicks on the link to the mirrored page, then his htaccess or whatever sends the surfer straight to one of his traffic trades.
As to emailing him, of course I have, but I've no reason to expect more then a "go fuck yourself" in reply... which is why I wondered what the SE's make of this kind of thing
