Any games hosted on Nutaku have to pass review at MindGeek / Nutaku's compliance department. Who actually makes the changes (the compliance department at MindGeek, a Nutaku team, the original developers, or some other third party) is information that is likely not made public. What's clear is that the edits in the censored scenes are of lower quality than the rest of the text, suggesting that the original translators and editors were not consulted.
