Where do you find these uploading groups?

So the public ftps (public by the fact that I can find them through napalmftpindexer) that are like

/tagged_by_Ripper/432/65332/fdsal/Adobe_CS2

Those ftps are hacked ftps or zombied pc's right?

I just always assumed they were.

Sometimes it get to the Bittorent's sites so quickly it's hard to imagine that it went through all this long process though.....
