People lose website account credentials, with meaningful life impacts, all of the time. Even simple image ads that are fake "click here to login" have tricked my elderly relatives before. I install an ad blocker on the computers of relatives out of reaction to real events that happened, not paranoia. You were never clickjacked? Never had pop-up or pop-under ads/windows created without your consent? Recursively? Crashing your browser? Never visited a page that was hijacked with an iframe? I've experienced a lot of malicious ads in my time on the internet, it baffles me that someone has not.
