This would be OK You could not have spam grouped together with a good file (afaik)

As for filtering spam (and viruses) ... let's just say it's been worked on, either as a e-mail type spam filter or a size filter ... which has been discussed most recently in http://www.gnutellaforums.com/showth...ize+and+filter

which might interest you.
