Oh the ping helps a lot! Somehow in some way. Or maybe not.

Blocking this host in your firewall might not be a bad idea but it doesn't really help to filter the results from this host one bit. That's why using PeerGuardian is fairly useless for Gnutella (and just opens another can of worms). It's about time that the LimeWire developers return from hybernation and add such (unfortunately) essential features as *internal* support for IP block lists. And I'm not talking about such bullshit as "Right-Click->Block Host".

If you wonder "why?". Simple, would you let a vet anyway near your guts? I, for one, wouldn't. The right solutions for the wrong problem never work.
