Transmission Bittorrent client, now with built-in IP blacklists

I was delighted to learn that the new version of Transmission now supports black listing using the Bluetack level 1 list. What this means is that with the black list engaged you will not get hit by scan attempts from certain known IPs that frown on Bittorrent usage. This was already available through PeerGuardian, but it is nice to have it built into the application.
