Looks like this one is hosted by Hetzner in Germany. Their abuse email is abuse@hetzner.de
Unlike the last one, it looks like this one is actually hosting the images for the comics rather than just using Webtoons/Tapastic servers, so unfortunately Webtoons can't just prevent image embedding like Tapastic did :/ However, since they are stealing featured series, it would probably be a good idea for Webtoons to throw some weight at them.
