Of course, it's possible people actually used these strings as passwords but applying a bit of Occam's Razor suggests that it's simply parsing issues upstream of this data set. In total, CynoSure Prime identified 3,472,226 junk records which I've removed in V2. (Incidentally, these are the same guys that found the shortcomings in Ashley Madison's password storage approach back in 2015 - they do quality work!)
