should +R prevent unauthenticated users from joining the channel?

Right now, it looks like +R allows unauthenticated users to join the channel, but forbids them to speak.

It seems like we should prevent them from joining altogether, because they can still spam the channel via NICK changes.

+r -> (channel mode) prevents users not auth'd with services to join a channel(ircd-seven) that has this mode enabled;
+R -> (user mode) prevents users not auth'd with services to PM(Unreal) you, if you /mode <me> +R;

Note: irc/modes/modes.go defines +r as "Restricted" but we don't use it anywhere yet.

Yeah if the mode already forbids them to speak, it should forbid them from joining as well. I believe the 'logic' there is that really it 'bans' those users from the channel, and banned users can't speak or join the channel.

Should an invite except you from this restriction?

[slingamn]

I'm going with "yes".
