Basically, that site is trying to stop people "stealing" their bandwidth. A ludicrous idea in any case... but the way they've gone about it is to say: If someone requests this image and they're on impawards.com, serve the image... otherwise don't serve the image.
If you have a small limited bandwidth hosting package and some big pictures, it doesn't seem such a "ludicrous idea" when some fusker accounts for 90% of your bandwidth. I prefer to serve some tiny .png indicating that the image has been stolen rather than just a simple 'request failed', but hosting costs money and it's up to the people paying the bills how they handle hotlinking.
URLs are forever not just for Christmas.
How many redirects would you need to manually add to the .htaccess? I can see why automatically changing thread URLs to something like lfgss.com/thread_title would be a PITA, but for the small number of important/popular threads it wouldn't seem like a big imposition to create the necessary redirect.
