many of us wish to download such or such file, but when the search list appear, we know there is a problem. For instance a music video will be about 40mb so when I see results with a 29.0kb, we know there is a problem. I check the file with bitzi and here we go.

Overall
-3.2 "Dangerous/Misleading"

When some users are sharing such files, obviously their intentions are to damage your computer, so I think we all agree that no one wish to share with them, so why not create a buttom that will alert LW that this user is sharing viruses under falses names? Once LW is alerted, then that person could be barred from accessing LW and one by one these people would be removed and LW would become a very nice place for any file sharing.
