this one is quite amazing, I expected it to be one of the weakest around today, I certainly would include it in one of my first attempts if I tried to brute force any password.
There’s no guarantee those accounts hold any value, though. A throwaway account is the perfect chance for such a password — you won’t forget it and won’t care if you lose it.
Also I wonder if Randall Monroe knows this somewhat ironic fact? It would make a nice addendum to the alt text on https://xkcd.com/936/ (which BTW is the origin of correcthorsebatterystaple for those wondering).
