Even if you have a firewall whether it be a hardware or software one, when you run a p2p client
people will be able to connect to you via your client. The p2p client acts a bit like a tunnel. Ok, they can't get access to your machine, but they will know about everything you are sharing and downloading. The only way to sniff them out is to keep the banned IP list up to date. In fact, the peer firewalls mentioned in my report both have screens which will show you if a banned IP address (the spy bot), tries connecting to you.
'identity or abuse??'...... sadly, probably both :
