My mom called me because her tablet was broken, it turned out the news website had a giant overlay with some heartbreaking story that they relied on ad sales and due to her evil actions, they now had to lay of people. I whitelisted the site and it worked for a day or two, then my mom called me again that her tablet was still broken. This time that same news website had an overly aggressive full-page overlay ad that she couldn't figure out how to close. A third time she called me her browser kept crashing because the news site was attempting to load multiple MB of JS and video ads.
For my parents it's ads, not scams that cause the most problems.
