IP to Phone Number (Score 2)

They can talk about 'trusted partners' and 'optimising websites' all they want, but the main point here is that they are sending your phone number over HTTP. Anyone on a hop along the way or of course the end website and their 'trusted partners' can now link an IP address to a phone number. Via other cookies they can tie that IP address to your previous ones and suddenly they have a Phone Number to go with the previously anonymous browsing history and customer profile.

Just imagine if that irritating banner ad could actually call you! It really is a phenomenal breach of privacy and security.
