Would be nice to see some updated Default filters.

The adult-list if far from complete, and I think, should be split in to three or four categories. (e.g. "normal", illegal (<18 and such), perverse/extreme, ...). I'm pretty sure there are normal users who search for adult material on Gnutella but do not appreciate seeing the latter two categories I mentioned.

The Spam-filters could also use an update. They block some spam, but certainly not all. Will a few tweaks and updates, it could block much more spam.

Even better would be if the filters could be auto-updated (http or though gnutella), which would provide a much more timely and effective anti-spam mechanism.
