I'm not sure but, if this all sends requests from a single domain; it will be treated as a visitor-tracking-malfunction issue. I wouldn't like that if I'd have ads or related stuff like that in my site customized and viewed through here.

I do my best by forwarding the client through with x-fowarded-for however it's completely up to the provider.

That said there's nothing to stop the haxx disabling/hiding ads or the visitor running Adblock for that matter.
