Most chances are owner is running MySQL server which contains all information on bans, hacking it isn't easy and won't be done for free, I suggest you to head to deep web and hire a hacker or check out forums, one of the forums is ex0dus, you can buy services there or offer a job, you can also check out Google of Qusemett.
Probably you found source code from ****** which may not be accurate and contain different information. There's a chance main owner or developer (or whatever he/she/Apache is) has their own server in which information is stored. If I'm sure, most databases use additional codes for login too.
