The one that took data from PBFs and did the PK lists was by Gabe. It's still up at [
qhcf.net] but it hasn't been updated.
I started writing a PBF spider but got bored. If there's interested in one, I'll try to finish it. I just got tired of writing all the regex for it.
The one I did was just a spider for Dio's graveyard so I could see what race/class combos were (un)popular. I've also got a script to parse identify/lore that works 90% of the time or so, if anyone wants that.
