Have you ever heard of Overpeer? If not, google it. I'm sure there's similar groups sponsored to specially pollute gnutella with junk & viruses. Since they use the same technique as the autospamming, autogenerated spam results It is no doubt similar groups of people. Advice is to ignore files less than 1 (1,000 KB) or even 2 MB (2,000 KB) unless necessary. And re: porn; depending on which gnutella program you're using, filter out these words Direct instructions to eliminate porn from results such as using keyword or result filters.
