kazaalite 2.0.2 is good, but they've disabled the participation hacking.
I've sort of found a work around though.
Connect to kazaa. Don't download anything, and set all your upload restrictions to be very lenient (unlimited bandwidth 10+ connections etc).
Let it run for a while and let your rating go waaaay up.
Go into regedit and export the
[HKEY_CURRENT_USER\Software\Kazaa]
"LastSearchHash"=hex
big bunch of numbers here)
key to a file. This is your user rating. Turn your normal uploading limits back on, and download whatever you want. When your rating goes to hell again, just import the saved registry entry
Some day I'll be rich and famous for inventing a device that allows you to stab people in the face over the internet.
