AoRF's yo.pl. It's a script that does horrible things to the 4chan boards.
The Touhou hijacker is a regular imagedumper, except that it appends random garbage data to the first file (the "TOUHOU HIJACK LOL" one) to avoid duplicate files. Customizable, but there's nothing special about it.
The awesome options are the ones that read a list of proxies and create a thread for every single proxy on that list. Thread dies if it detects it's banned from 4chon. The proxy list is supposed to only contain working proxies, but I just added some more error codes to make the threads die so I can throw random proxy lists at it. Drawback is that for a large enough proxy list, perl starts consuming stupidly large amounts of RAM. sagebomb is particularly effective; I could easily get 1000 sages on guriin's threads for kicks.
There are also some other really awesome options I was never able to work, I just get random errors. Broken proxies on the list probably screw things up for those.
