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.
Except one guy isn’t. You have to choose to install the software. It’s not included by default. I’m running a local client (Voyager) and never dealt with any of that because the admins of my instance don’t use it either.
