Perhaps this feature already exists in a newer version; I'm using 2.1.1

I'd like to be able to block search results for specific IPs to filter out these jerks who manage to place a referrer file in every search result list. For example, if I search for "zxcvbn" and "Any Type" I get 3 results; a URL, an HTML, and a MPG, all from 194.213.194.237. Obviously these aren't real files, and I'd like to make this spammer "disappear."

Just my 2 cents worth.
