there should be some sort of tag, maybe a meta tag, for western style that works similar to the categories on sadpanda. i dont want to see anything from a western artist or in a western art style or from a western copyright, and the site has gotten progressively more full of those things over the years in my experience. to take it a step further i personally would like a tag that functionally could filter everything that is not a jp source. but i think something that works like the first example makes a lot of sense for this site.
