A common motivating concept for decentralized is no authoritarian oversight to deplatform you.
You're seeking editorial influence (control) from the start.
Setting aside what users want versus what you want, as a platform technology you need to be careful here.
You way want to brush up on the safe harbor laws for Internet infrastructure/pipes/hosting firms and technologies versus the lack of safe harbor for platforms with desire or ability to exercise editorial influence or control on a user or content basis.
You can navigate this, by having reasons such as "I'm not editing, but by associating users with a non-anonymous identity they will self moderate", as you've noted. You can, with such reasons, still have a bit of cake after eating it. But be careful not to veer into actual editorial control unless you're prepared for full liability.
Potential legal issue that needs addressing at some point.
