hmmm.. at first when I saw the site I thought it was scraped content (thats content stolen from other sites in order to show google that there is content on your ad site). But looking more closely it does look like a proper community. I can see they tell people to upload rpg ressources to share with the community and they of course have a disclaiming about "not being responsible for what people upload/say/bla bla bla... " This of course doesn't mean that they shouldn't remove copyrighted content if asked to do so. Most of the maps in here are under CC license and under such MUST have artist credit, so I'm guessing the right thing to do is to tell all mappers in here to go look if any of their maps are on the site and if so, demand it removed or credited... (doesn't look like they can handle crediting though - but that's their problem.
