22222323-ATProto currently supports 2 identity standards, did:web and did:plc. These are both potentially problematic for long-term use by users who may be the target of censorship: A did:web ID depends on the continued cooperation of a registrar and the nation state that regulates it, as well as suffering from more mundane issues like forgetting to renew or being priced out by registrar fee increases. A did:plc ID depends on a centralized server, and we have no guarantees about its future behaviour.
