V, There's a difference between linking random, WTF stuff and starting an image thread with a clear topic. The link thread exists to cut down on people posting individual new threads about the same old Internet phenomenon they just now discovered for the first time. Remember when people would make new posts each time for some funny video or article they just found? Remember when that was every other thread? That's what the WTF link thread is for.
Also, if i concerns you that this thread is just a lot of big images, just add a high-bandwidth warning to the thread's title and nobody should have a problem with it.
