Months ago, a blurb about this story first came out. It was speculated that BT, one of the UK's largest ISPs, was secretly using DNS redirects to gather information about their customers. The company denied it up and down, but earlier this year that was discovered to be a lie.
Now BT has been forced to admit they secretly trialed an advertising targeting platform using customer data, although on their defence they said no personally identifiable information was "processed, stored or disclosed." As had to be expected, the ISP is currently facing many angry customers who might sue after discovering that BT partnered with a company known for peddling spyware. What would you do if similar information was discovered about your service provider?
