I'm not suggesting that you not create a tutorial. There are some cases where
this could still be useful. If you create a tutorial though make it clear
that you are * not anonymous to Freenode *.
Users could probably get some limited anonymity back by registering a nick
from a free hotspot. However users should be warned that doing so will still
reveal general location information to Freenode and anybody else who can
force freenode to reveal.
There are some attacks which can be performed knowing general location data.
People in rural areas are most at risk. I believe drug dealers for instance
are an example. While this may be a bad example it is one I know of and I
believe other civil rights and similar individuals fighting governments in
other countries are also impacted. Basically the government can see who in a
given area is using Tor and using this general location data (say Bummblesaw,
Wyoming, USA) go after the only user in Bummblesaw, Wyoming, USA.
There is also another attack which can be performed for this group. If I
recall correctly it is recommended such users use bridges as this offers some
level of protection by making it more difficult for governments to identify
Tor users in a given area.
