I can't believe people care enough about a videogame (or a console) to spend time placing spoil votes on review sites (whether for PS3/360Wii or whatever games).
Really bizarre and rather odd/sad IHMO. What could possibly motivate such responses (outside of DRM for Spore, etc.) I can get that, but why to games like Halo, LBP and others attract this kind of faintly psychotic reaction?
Try to be reasonable... its easier than you think...
