List of IRC/chat networks that block or support Tor

Some IRC networks, by policy, don't allow access from anonymous users. Mostly, they do this because some (but not all, or even most) anonymous users are jerks, and most IRC software doesn't provide a way to block jerks more sophisticated than blocking them by IP address.

Becoming unblockable by target services is not a goal of the Tor project; see the FAQ entry on why this is both difficult and undesirable.
