If you download movies and TV shows from 9anime, your actions will be considered illegal and you may face penalties for it.
In addition, there may be some kind of malicious link that can damage your computer easily during the download process. Therefore, if you don't dare to take the risk, you should instead stream your movies on legitimate sites.
9anime and its alternative websites have been leaking the content of popular TV shows and movies for a long time, and the trend seems hard to stop. However, to protect the interests of producers, directors, and actors, governments, especially in the US and Japan, have taken more extreme measures to reverse this trend.
Infringing or helping others to infringe and download copyrighted content from illegal websites like 9anime is now considered an offense under the privacy laws of the world.
