This is how I am already configured, yet it's been a problem from day one (well over a year, maybe two).

No need to be paranoid; it's almost certainly a "bug" or someone found a way around the restriction. No organization is going to waste their time downloading dozens of copies of perfectly legal and obscure video files just to "log-jam" Gnutella. It would also be an absurdly slow and inefficient means of addressing the problem of piracy (not to mention that I still use Kazaa on ocassion... which is a much higher profile program when discussing pirarcy... which does not experience this particular problem).

No, I'm more certain that LW can be easily fooled by letting one user connect from multiple IP's.
