The letters are a bit tweaked up, but it's based on the font "House of Death." Hopefully you're asking because you're making a ZP tribute of some sort, and not a logo for a competing pumpkin site.
Oooh, in that case I can provide you with the vector file for the logo if you like.
Although it looks like you pretty much nailed the lettering already. If I were to take a guess, I'd say that maybe you used the logos from one of the PDFs available on the Disgusting Downloads page?
I thought about doing that But I needed the dot com to look right so I found the font and just tried to edit it like you did. and I have a bit of a font addiction.
