Hello sirs. I've been in communication with a user who feels that my block of
his IP address is inappropriate. E-mail correspondence follows.

Hello,
213.216.199.14 (
Tuira-P1.suomi.net) is currently blocked, with the reasoning
being that it's suspected to be an open proxy.
This is indeed a proxy (but not an open one - or at least it's not
*supposed* to be, I think), used by my ISP (Oulun Puhelin Oy, a.k.a. Oulu
Telephone Company, Oulu, Finland). The thing is, it's a transparent proxy
that the ISP uses by default, and I'm not aware of any way for the users to
disable it (aside of using any other port besides 80, of course).
The proxy has been blocked a few times before on fi.wikipedia for vandalism.
The host name suggests it's a proxy for the users of Tuira region in Oulu,
and since I'm not that close to Tuira, I take an educated guess it handles a
huge chunk of the northern Oulu (remember, I'm not really that familiar
with the ISP's inner working, just guesses). I'd *hate* to drag every luser
in this big neighborhood out of their homes and ask them nicely, with a
baseball bat, if they have been adding crap to WP. There *has* to be a nicer
solution to this than that, right?
There's an unrepentent vandal in the neighborhood. What a scary thought.
Maybe I should move to Siberia. Meanwhile, maybe I need to edit from the
university =(

If what you said was true, I would not have been able to perform this edit

Sorry, your IP is a Tor proxy.

All right, so my guess is there's some Bloody Idiot in the neighborhood who
runs a Tor node, 80/tcp traffic comes out of that host and gets intercepted
and forwarded by the ISP's proxy (that *every* customer is forced to use, I
remind you again).
In other words, the blocked IP is, in my educated guess, *not* the Tor node.
It just unwittingly hides a Tor node behind it.
So what exactly are we going to do here? Call the ISP (who are a Phone
Company, I remind you again) and ask them to remind people that
running Tor is very, very stupid because it makes rest of the customers
unable to edit Wikipedia? Or ask them to take fascist measures to make the
people not to run Tor exit points from home? Or move to Siberia; goodbye,
cruel world?
I'm not questioning the wisdom of blocking the thing if Tor traffic really
goes through here; all I'm saying this causes a lot of collateral damage.
And what am I supposed to do now? Look like a Chinese dissident and use
Privoxy, the most incomprehensible program devised by mankind since the
advent of Sendmail? I would rather not try to specifically avoid IP bans
even if I'm supposedly the innocent party.

Still on the open proxy issue:
It seems that the proxy does provide a valid X-Forwarded-For header. I made
a small script on my web host that spits out the HTTP remote address and
X-Forwarded-For header, and got 213.216.199.14 (
Tuira-P1.suomi.net) and
82.128.217.58 (
addr-82-128-217-58.suomi.net) respectively, latter of which
appears to be my correct IP.
Now please don't tell me Mediawiki can't block based on X-Forwarded-For.
This is the year 2006, after all... =)

So, I'm wondering whether this is a shaggy dog story, or blatant trolling,
or possibly an alibi with plausible technical merit. I was about to post
this to [[WP:BJAODN]], but a fellow administrator referred me to this list.
All I know is... if *I* was able to make a sandbox edit of "Tor proxy ~~~~"
using his IP, anybody could just as easily the IP for abusive purposes.
Suffice it to say I don't know what to tell the guy.
