Viki and Netflix are the only legal sites in Germany for Asian dramas. There a tons of illegal sites and you could say, okay, that's their risk, if they are streaming dramas without a proper license. But since April 2018 streaming is illegal for private users, too. The European Court in Brussels, Belgium, has decided, that streaming is now illegal and forbidden. Right now, there are not that many instruments for pursuing all those private users, because while streaming your IP is safed just temporarely and as soon as the episode or movie is over, your IP isn't safed anymore. I'm not talking about sharing services, just streaming sites, so if you don't download anything on those illegal sites or have an account, where all your streamed dramas are visible, you probably have no problems. But I guess, it's just a matter of time and lawyers, specialised in cease-and-desist orders and the legal streaming sites will find a way to pursue those private users. This is a profitable and big cake for them.
