Public Tor exit nodes are banned on the network due to abuse.
The AnonOps IRC Network does allow access through a Tor hidden service leaf server which users have to be manually added to by network administrators, but only after prerequisites are met by a user. Simply connecting to a standard server or via the webchat to the IRC network will result in an error message and a failed connection.
In order to be added to the Tor leaf, network administrators ask that a user register a nick and actively use the nick for a minimum of three days to show a genuine interest in using the network regularly.
The user is also asked to develop a basic knowledge of usage commands needed for IRC networks which includes learning the connecting user's identification string in the format [email protected] and understanding what each part means. To see an example of this simply /whois yourself. The first line displays your nick, username(ident)@AN-l33.k38.9vuj2o.IP (your cloaked ip/hostname - it will be random).
When, and only when, these prerequisites are met, a user can join the #help channel to request tor leaf access. Admins in this channel will briefly assess you; if they feel you cannot adequately complete the setup process due to a lack of knowledge then you will not be added.
Unlike help given for other topics, setup and configuration of IRC clients to work correctly with Tor is considered a more advanced subject and it is therefore up to the user to self-educate in these matters as step-by-step help will generally not be given.
