Did you receive notice of the change? If someone changes something like that, it's common curtesy to email the artist and let them know, and the reasons why. That also gives you someone to negotiate with about the change. I don't think anyone who gave a good look to the render could mistake the tats as blood. And the supposed amount of violence is so minimal that I can't see it deserving a violence rating. As for inconsistancy, remember that the mods react to complaints more than anything else. They don't have time to evaluate every picture as it's posted. So if someone complained about it, but not the other pic mentioned here... Although now that it has been mentioned, it'll probably get both flags slapped on. I suppose it could be a glitch in the 'sity's software.
