What got me upset was the fact that I respect users privacy, and to find out about this behaviour from a bug report notification pissed me off. In /code's defence, at that point, it was basically /., /.JP and Burrapuento as the last three slash sites on the internet so a lot of slashdot specific functionality has creped in over the years before the code drops stopped in 2009, with the documentation for independent sites being a bit stale.
EDIT: I've written a follow up on my SN journal: http://soylentnews.org/~NCommander/journal/277
I'm just glad to see that a lot of GNAA and other crap has largely stopped.
Still see the Golden Girls spam posts, but, out of all the possible crap you could be clogging the internet up with, the Golden Girls aren't a bad way to go.
