As part of the devs farewell message on their site, they have included malicious code to make each visitor sends 2,000 requests to the dbzer0 servers in an attempt to DDOS and take the instance offline.
It was a very sloppy list. I searched for a few regex terms and there definitely some who only matched two nicks and were way to general for that. For example blocking every nick starting with urheber, which is German and means originator, to just match two accounts who are exactly named like that. It could also be that he put some nicks in the regex just make the block less obvious
