LW (or any other Gnutella client) can't be held responsible for fake files & crap being shared on the network.
It's peer-to-peer. How is LW supposed to control what's being shared?
If Azureus is working for you, that's great...keep using it. Why bother to post a rant here? If you're not using a Gnutella client, there's no reason for you to post here.
