Spammers. That means you're using an old version of LW. Update to LW 4.12 & that won't happen again. You will get those fake results showing up but it won't send you to a site. http://www.limewire.com/english/content/download.shtml
You'll never connect to those fake files so beware of them. If you select to downld them they'll just go to need more sources after spending ages trying to connect. Generally those results are like 100 for one, 99 for next, etc. instead choose those with 10 or 20 results under the # column of the search results.
