Best way to get account Dumps

Hey i was wondering how do people get account dumps, do they add a backdoor to something or what?

I know the user is banned, but here is the answer for the people who doesn't know.

This is the way I do:
My combo lists are very strong, if I should say it.
They're updated cause I use the newest database leach from what I can find - also there are some very good databases with alot of passwords that haven't been changed.
So no, I don't think any of us are "adding a backdoor" or something.

I have a few modified word lists that are about a gig in size each which are good for parsing.

They get it from fresh database leaks or purchase it peopld on orivate grouos or forums,

Creating a good combolist are a work of a good cracker so i salute them.
