Or get Peer Guardian (or a good software firewall) and a list of intenet cop IPs and BLOCK them!
It won't make you 100% safe, but couple that with the privacy protection in KL++ v2.1 (unlistable shared files) will make you an unlikely target to anyone BUT your ISP. Your ISP could log your internet traffic if you're being a major bandwidth leech, but that's unlikely if you're looking for rare files and you limit your upload bandwidths to less than max for your connection.
