Many of these accounts are from Brazilians (like me) who use shitty passwords (unlike me). I checked a few of them and they seem legit. I was even able to log into one of the user's hotmail account, it was a real person. Not saying all of them are, but at least a few arent.
It is not that I care or that I think that you did something immoral, IMO you didn't harm anyone but it is still probably illegal (obviously depending on the jurisdiction).
