Hello All

Been using LimeWire for some time and hearing all this bad news about LimeWire and other Peer-to-Peer users getting busted for downloading music and other questionable "bootleg" items using LimeWire I am getting a bit worried.
Is there an official buzz on this? Should we be concerned?
I am running on a Mac which loads a FireWall upon boot up and also have a router (though not sure if I can configure it to also act as a firewall mechanism. But if FireWalls are in place how does LimeWire get files to download/upload through them?
How are people getting busted using LimeWire and how do we prevent it?
I read some universities are actually banning LimeWire use. How are they finding out who has it and when and for what purpose it is being used?

I have stopped using LimeWire until I can get a clear idea of my safety using it or until someone can shed a better light on these issues.
Thanks for any replies.
