here's another suggestion (a semi-serious one)
if someone has forgotten their iPod screen lock code, why not just send them this "Let Me Google That For You" link:
http://lmgtfy.com/?q=forgot+my+iPod+screen+lock+code
then they're doing the research themselves :)
joking aside, as has been already pointed out by several people, this information is readily available - they don't have to find it on this site, and in fact they'll probably find more detailed descriptions elsewhere. Even Apple provides the info (and even the software to do so). of course the context under which Apple answers this question is not "what do you do when you've stolen an iPod", but rather they answer the question of what to do [http://support.apple.com/kb/HT1350|if you can't unlock your iPod...]
to me the significance of this particular issue seems lower than the amount of discussion here would seem to indicate - there are far more significant ways to aid a criminal. As well, what's to say that giving someone info on how to clone a hard drive, or replace a hard drive, or replace the case of a laptop or iPod (where the serial number is visible), ... etc etc -- isn't ''possibly'' helping somebody who has stolen something?? we can't possibly know here. so do we ban those repair topics too?
that said, I'm not against putting the answer "behind the counter" as Ben suggested, that at least clarifies ifixit's intention that we're all here to help people ''with their own devices''
