Here's an idea about blocking IP addresses though I'm not sure how practical it is as there may be flaws in the concept.

One guy mentioned right clicking multiple listings of crap files in a search to block their IP addresses. If these IP address could be transmitted to a server of Limewire's and stored and counted as to which IP addresses are blocked then compile a list of the most blocked IP addressses that Limewire can download and auto block upon startup of the Limewire program and thus filter out malicious Limewire users before you even start searching the network!

Something similar to Peerguardian but integrated into Limewire's program. Just have a user created blocklist everyone can choose to use or not use.

Anyone other then me like this idea?
