Netflix has confirmed that several upcoming anime titles have leaked online, including season two of Arcane and Terminator Zero. The leak is attributed to a compromised post-production partner, with footage from multiple Netflix titles appearing on platforms like X and 4Chan. This is not the first time such an incident has occurred; similar leaks happened in 2017 when scenes from Orange is the New Black's fifth season appeared online.
