I've noticed that I will be monitering my connections and someone will try to download a complete folder of music at once. I find this very rude because then other people can't download what they want.

Does anyone else have this problem?

I use Tiny Personal Firewall's rules to allow or deny IPs from connecting. You can make it prompt to allow or deny a connection and set a rule to deny someone who has queued an entire album or multiple albums by an artist.
