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.
The issue is that it's one person shadowbanning people without their knowledge for any arbitrary reason across instances. Like even if it's opt-out, that's still problematic since it makes the default experience whatever that one person thinks it should be. Why should one guy get to decide across the entire fediverse whether your posts are opt-in? That is antithetical to the very concept of the fediverse.
