A page with a page title and URL made only of squares is one of our top performers. Why?
The above image is from my Real Time > Content report. Every so often (maybe every 10 days on average, maybe a bit less), a page with this apparent URL/page title combo appears. Of course, we don't have any pages by this name -- I assume those are characters in another language that's failing to render properly.
Is this spam or a sign of a bigger problem? And either way, how I do I stop it from infecting our reports? How do I type a square to set up an appropriate filter?
