Does anyone know how effective it really is ?
It stops the traffic if that's what you worried about. As for saving you from prosection, that's impossible to determine. For some P2P protocols it might not make a difference, for instance bittorrent uses a tracker to keep track of all the connected peers so technically if the 'bad' guys can connect to the tracker they can get a list of peers and I would consider that good enough for prosecution since you're obviously participating even if they can't connect directly to you, whether your local courts agree is another matter.
