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.

Basically, every time you visit the page, it has code that sends 500 * 4 queries to one particular instance, making it load a page from the modlog, do a search, etc.
So everyone visiting the page would suddenly be sending 2000 queries each, and in theory, enough users would DoS the server by overloading it with those requests, rendering it unusable.
