They sound like the fake files being spammed on the network. If you get a total of results in the thousands then yes, they are fake. With say 100 for one on the list, 99 or the next file, 98 ... etc. And it is also an attribute for them to take a long time to "pretend" to try to connect. The best answer is to use Bitzi to see if they are real files or not. See How to use Bitzi Web Lookup
