Was thinking of something like a minimum word requirement for comments on images.
Basically, I look through the images and I keep seeing 1 or more people, on multiple images, simply going "Thanks/thx for sharing!", "Oh, that's so nice!", "Very sexy!", "Awesome background!", "Very pretty!", "So cute!", or just other really short comment that doesn't really have any real meaning besides spamming to add up credits or something. So perhaps to prevent such easy spamming, there could be some sort of minimum word requirement for the comment to be posted up. Like 10+ words or something.
