Incidentally, can a banned IP address still be used to browse the site and
download packages? There are many people who use Tor and other proxies for
various reasons and it would be a shame if they have to suffer due to one
basement-dwelling troll. Essentially only the login and post forms would need
to respect the ban.
Sorry if this has been addressed already. I haven't read through the patches.

That would make for a great post in the stupid computer mistakes thread... it
would be on the same level as ssh'ing into a box and killing the network.
