PussyTorrents.org is attached, I'll work on Empornium later. The third site is not in English which makes things much more difficult... I may not do it.
I took my first swing at multipaging with this script and failed. I have no idea why, so you'll just have to refine your search terms if you get more than 100 hits.
Also of note, this site pulls ALL results, even filtered (0 seeder) results, but then hides them in the browser. BitChe on the other hand sees them all, even if you normally wouldn't. I could add a check for each torrent to keep it from turning up so many 0 seed results, but most probably have that option selected in BitChe anyway.
Edit: Empornium added below and in first post. Awful searches on that site. Descriptions are searched, no way to bypass it, so you get lots of results and almost all get filtered out.
Again, I can't get multipaging to work. Will dig into that later.
