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.
Just before this whole thing, the piefed dev pushed an update that capped how many up/downvotes piefed users can do per day. They set the cap to effectively punish like 3 users who posted all day everyday.
One of those users had a "I will leave unless you reconsider." moment and they didn't give half a shit. And they didn't even make the list. None of their communities did.
So just a couple devs thrashing around causing as much collateral damage as possible.
