Hostiles List
Been discussed about a lot lately.
Other suggestions: Don't repeat same search term too many times (wait several hours or a day if repeated a few times already). Use the Get More Results option occasionally. If still problems, go to connections window & remove non LW version 4.18.8 version ultrapeers you are connected to. One at a time of course so you don't lose connection.
