Why is LimeWire unsafe?

Answer 1

Because Limewire needs to be added to your firewall's white list to operate effectively. This means the application is trusted, so any traffic coming through this application is trusted by the firewall. This creates a weakness in your security setup and an opportunity for hackers to cash in on this weakness.

LimeWire you connects you to 'bad' neighbourhoods often associated with porn, malware and piracy. These associations may have legal implications for persons who download data from these servers.
