I'm here.
It scrapes everything on the front page. Except the ones marked "all". Which I figured the sites have so little pastes, we might as well scrape 'em all. Some pastes aren't listed, so this picks them up. Pastebin will ban you from the site without that sleep in there, so. Anyway, you find some interesting stuff.
It seems a tad too automated for something that intricate. My guess is it'll grab whatever's in reach, regardless of content.
