Hi Receptional Andy, I meant it is "optin" for a website, for a "webuser" it is optout as you correctly state.

" You can detect and block phorm with varying degrees of efficacy as both site owner and internet user"

As a site owner I think it is impossible to block it as the packet inspection is done at the ISP level - of course you can block those IPS's who allow it via IP address, but in the UK you are blocking Virgin and BT which is a large % of the UK market - not really sensible.
