Modern XMPP project discussion - 2021-06-09

Hello, currently anonymous MUCs experience at least two issues: further LMCs of a message cannot be related to a specific user after going off and back online and blocking a user is only possible by its nick name+mucjid. What if the server, which knows full jids, generated hashes of all jids and kept arecord of those but also distributed them along side with nicks. Then the two issues were solveable client side werent they? Am I missing something?

This does in fact already exist.

I see :-)

So what's missing is probably more implementation and pushing that XEP forward in the standards process.

But the title is misleading, because it's pseudonymous, and it has privacy issues.

Ge0rG: Privacy in regard: other participants know when a nick changes and can know that a user participates with more than one client?

If all servers use some random salt for each muc, you may have different unique hashes per muc

ericus: each MUC should use a secret salt, or you could be tracked across rooms. Also if you leave a room and enter it with a different name, you get a new identity. That's broken by this XEP

What was the idea there? Throw in the nickname in the calculation?

The first part should or could be incorporated, the second one, what Zash said
