I have been getting porn spam disguised as other files. So I'd like to block the IP hosting these deceptive files from further searches. But how? Limewire FAQ says:

If there are particular IP addresses you wish to ignore (if, for example, a particular IP address was sending you unsolicited results), click under Hosts where you could enter that IP address into the “Ignore these hosts” window and click “Add.”

This would be possible if I knew the IP of the original file. Where is this information stored or displayed?

And it would be much nicer if I could, say, select a search hit and choose "Ignore Host" from a menu somewhere.
