Another way to ignore, is to rclk the user into the hotliist. Then they can be ignored. Unfortuantely, ignore is not on the browse screen, where users tend to make that decision (whois info is not accurate to the degree it doesn't tell you what the other person is using for shared files), but the option to add to the Hot List is.
I like leech hammer, for ignoring, because it is a simple clk of the hammer, with the perspn selected. This automatically removes of the hammerred entries, which simply ignoring doesn't do.
Also, if I am going to block or ignore someone, I like to have the satisfaction of hearing them get hammered
