Has this been mentioned yet? I'm not complaining (take that seriously please): have just been testing and observing. Ripped images in peoples' galleries receive points when commented on, but not when only rated, it seems.
(NSFW images may receive fractional points- I've seen someone go from 99.99% - I'm not referring to the no-salute 99.99% - to the next level after a NSFW image was commented on (by me; who's testing? :) Using text-based Lynx to check points and a graphical browser to do the rating or commenting...), but that may have been because someone else was rating/commenting on another image at the same time, of course.)
