I've been adding hosts and keywords to the filter list like mad, but I'm still getting loads of spam results. Perhaps it's time for a Gnutella-wide filter cache, rather like the host caches, to filter out spammers, scammers and bots. That way, each time you open your client, it would update the filter host list automatically and block'em all. Though, obviously, how this list would be managed and what criteria would be applied to add to it is a more difficult question.

Alternatively, I've thought of sending a list of spammer IPs to Bush identifying them as Al Quaeda members
