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.
My instance (diffrint) mirrors bans from blahaj and db0, and there were over 3000 instance bans from blahaj over the last year, so it's easy to get a list over 1k just in transphobes alone
