Earlier that day, she came from a doctor and ended up searching for a medical condition on a famous search website. After that, she started seeing ads for various bullshit remedies all across the internet. Almost every website she visited, showed her same types of ads. Even when she wanted to forget and take her mind of it, she couldn't because these ads were constantly reminding her of it.
She got so disgusted that she quit using the web for the rest of the day and cried.
I guided them on how to install ad blocking addons and how to change default search engines (she now uses Startpage) But we couldn't easily block it on iPad so the solution was to switch the search engine and clear cookies.
All these companies that make money off tracking people and are selling search results really need to rethink their business models.
PS: She also wrote an email to Tim Cook complaining about this and got a reply from someone that they will "look into it". I'm glad Apple will now a provide solution to block these kinds of things on an iPad.
