Unfortunately I think it's a bit more diverse than that. if we're referring to the same thing here. AREA is used for image maps, and I haven't seen one of those in ages, much less clicked on one. This is happening even when I type an address directly into Chrome's URL bar.
I'm also seeing it pop up on every site I go to, regardless of domain. Of the ones you mention, I've seen the issue on LinkedIn, Tumblr, NY Times, Forbes, Reuters, Google, Youtube, and Wikipedia. I haven't been to any of the others.
You've been seeing logs of this for ten months now? Wow. Very weird that it hasn't come up, I can't find much info at all.
