When faced with a question asking about the likelihood of getting caught for knowingly enacting a criminal scheme, the question should be edited to remove the criminal scheme context, and to remove the "would I get caught" portion of the question.
In this case, the original question was (paraphrased) "If I anonymously released a mod for my own commercial game, and that mod contained copyrighted assets to which I had no rights, could I be caught?" The edited question was turned around into "Is a game's author liable for copyright infringement in a mod which he didn't release".
As a general rule (which I know that I personally forget much too often!): Don't be shy about editing other people's questions in order to make the site better. Questions here aren't primarily about helping individuals (although they're about that too!), but are mostly about helping make the Internet at large a better, more useful place for everyone, by archiving great answers to common questions. If you see a bad question and think you can edit it into a good question, absolutely do it! :D
