The 10th most common password was far too interesting for me to ignore. While it is fairly easy to type, its not easy enough for it to be some sort of tap-password.

Having a closer look at the list, and assuming the dump is organised in some sort of chronological creation order, you can see that all the accounts which use that password are created in several tight groups, share a fairly common username theme (mostly female names), and use a fairly narrow selection of email providers. I would guess they were made by a bot.
