The original post does not work, cuz it utorrent would check cookies, so I've fix it first
After fix the script, the script could fetch correct list and remove torrent and data correctly.

Second, I need find the oldest torrent, but the list structure is hard to sorting
So I try the dummy way ( But it save some coffee time for me :p )
Just find the oldest torrent and remove it.

Cuz I need the script for free the space automation,
So if the space still occupy, just need call it again. :p

It's dirty, but worked!
