In which case there's no implied consent for cookie authenticated sessions and no way for web masters without access to the robots.txt to opt out of Phorms profiler.

And until we're told what this will be, there's effectively no opt-out for site operators most of whom want publicly accessible pages to be indexed by google. Few want a 3rd party performing unauthorized interception.

3. The user agent (if any) used to match lines in the robots.txt file. (Maybe googlebot but who knows??)
I'm pretty sure Google would action that.

BT's hand waving about opting out is exactly that, those already in contact should start pressing them on it
