How top health websites are sharing sensitive data with advertisers

Fun fact: It happens when you shop, look up information online on Google etc. It is because all the websites are infested with trackers/ad-tech. That’s how they make money!

Use ad-blocker. I’d do a post on the adblocking some day.

Some of the UK’s most popular health websites are sharing people’s sensitive data — including medical symptoms, diagnoses, drug names and menstrual and fertility information — with dozens of companies around the world, ranging from ad-targeting giants such as Google, Amazon, Facebook and Oracle, to lesser-known data-brokers and adtech firms like Scorecard and OpenX.

Using open-source tools to analyse 100 health websites, which include WebMD, Healthline, Babycentre and Bupa, an FT investigation found that 79 per cent of the sites dropped “cookies” — little bits of code that, when embedded in your browser, allow third-party companies to track individuals around the internet. This was done without the consent that is a legal requirement in the UK.
