While I'm sure this might seem like a good idea to you, it certainly isn't.. unless of course you want to rid the Gnutella network of all the good files as well. One very important factor is exactly that you cannot just print out logs of what users are sharing. Keep in mind that Record Companies and Movie Studios would love for that feature to be implemented also.

How many people would be sharing their music and movies if they had to be on record for sharing them. Not many I bet.

... and yes the keyword filter here is a pain in the @ss, but I think most people can figure out what that 4 letter word is.

What I would suggest is using the keyword filter and just block the results that contain these words.
