I've had an update on this. As you know, as soon as you alerted us to this we started investigations into how this might've happened.@Gel - Sorry you had a surprise this morning. You are one of only around 250 customers who are connecting to the RIN network, as part of the trial we ran between February and September last year. RIN is BT's Retail Network that we were trying out on a trial basis. The RIN trial is unconnected to BT Webwise and it looks as though a configuration error was responsible for the presentation of the Webwise screen. This configuration was put right as soon as we were notified and as we understand it this has been confirmed as the only instance of this occurring. As previously stated, customers using RIN on Plusnet should not see the BT Webwise invitation screen or be able to join the BT Webwise trial.
We can confirm that no further Plusnet customers should be presented with the BT Webwise screen, and that our customers' web traffic will not form any part of the BT Webwise trial.
As I mentioned you can change your connection settings to (username)@plusdsl.net to connect to Plusnet Centrals at any time.
