With all credit going to Soulkeeper (http://forums.slimdevices.com/showthread.php?94286-How-to-hide-forum-threads&p=699958&viewfull=1#post699958) on another forum:
If you use Firefox and Greasemonkey (https://addons.mozilla.org/en-US/firefox/addon/greasemonkey/), here's a script which inserts an ignore button for every thread. I'm playing with it now and there doesn't seem to be any performance hit on the forums. That could possibly change if you start ignoring more threads, I don't know.
This seems like it would work really well in the contests forum as opposed to posting "thanks" in every thread. One drawback would be that if will not fill up the page with non-ignored posts. In other words, if you had forum settings for 50 posts per page and you ignored 40 of them, you'd see 10 posts on that page. That's not necessarily a bad thing though.
Save the following as whatever.user.js and install it into Firefox:
// ==UserScript==
// @name Hide vBulletin 4.1 threads on RFD
// @description Ignore threads in vBulletin 4.1
// @include http://forums.redflagdeals.com/*

Edited to account for different code between the original and RFD forums. Might tweak it a bit more later.
