I'm not afraid to come straight out and name Virgin Media.

Their statement on the subject states that...

It may be that, as part of the evaluation process, we want to test the technology among some of our customers but we are not currently doing so and we will not conduct any such tests without individual customers' prior consent. Moreover, should Virgin Media eventually decide to roll out Webwise, customers will not be forced to use the system.

...which carefully avoids stating that they hadn't previously run any trials and uses the phrase "not currently" to describe their involvment in the trial process. BT could make the same statement.

It may be time for VM customers to demand clarification in plain English rather than trusting their ISP. After all, those of us who are BT customers used to trust our ISP.
