I had the same problem–I'd see lots of tiny, same-size files repeating my search criteria. So, I started to "block host" every time one popped up. Now, they're rare.

However, it seems that blocking these hosts has also reduced considerably the number of hosts with .mp3, .wav and .aif files to share.

At last count, my number of blocked hosts is in excess of 300.

I wonder if there's a way to search an individual blocked host IP address with LimeWire in case I should leave it unblocked, to access tunes?
