On YouTube, there are partners from which we can view full anime episodes. An example is Funimation. You can watch full episodes of anime such as Full Metal Alchemist, Shakugan no Shana, Nabari Na Ou and many other animes. My question is, would this be illegal and if so why?
Also, how do you tell if an anime streaming website is legal or not? Do you decide based on the criteria "if you can watch it for free, it is illegal", because I strongly disagree with this. Sometimes, it can be legal.
