The relay is the most straightforward way to access OFTC over Tor. Users who are accessing OFTC via the relay are not considered by OFTC to be "registered" by default, since their registration is with infrastructure rather than OFTC infrastructure. This produces a problem because Tor's OFTC channels are configured to disallow any user from joining if they are not registered on OFTC infrastructure. (I tested #tor-dev; I assume the others are similar.)

Usually, this kind of policy is intended to mitigate spam attacks. However, historically none of the spam attacks against IRC networks have been routed via infrastructure. This may be because has its own rate-limiting mechanisms for account registration (e.g. a reCAPTCHA test for each new registration), and it may also be because is new enough that spammers haven't paid attention to it. In any event, I think it's highly unlikely that you'll see spam from infrastructure if you permit users to access your OFTC channels.

Documentation on exempting users from the registered nick requirement is at . Any chance you could do this?

We don't have a component for IRC changes.

I've asked about this ticket on the #tor-dev IRC channel and tor-dev@ mailing list.

One way to move this forward would be to figure out how to do this on oftc in particular.

(The docs you point to seem pretty generic, and not straightforward to apply to our channels on oftc.)

I'm really not sure which component this belongs in.

I don't think it's technically feasible to accomplish this. The IRC channels are restricted to registered users using a CMODE (channel mode) like +R, which says:

R - client may join only when registered and identified to NickServ

There's no way to do exceptions to this based on host masks, which is how, I assume, we'd detect people coming from Matrix, but even that is unclear to me.

So while I understand where you're coming from, I don't think this is actually feasible.

One thing that *could* work slightly better is setting the channels +M (client may speak only when registered and identified to NickServ) and then maybe +v (voiced) would allow operators to apply exceptions for certain users.

But then we need operators to pay attention to joins, and that's unlikely to work...

Anyways, sorry about this, but I don't know how else to fix this. Note that it's possible for users to register with OFTC from Matrix. It's a little inconvenient, but it's possible, so that limitation can be worked around by users themselves.
