How about trivia in different languages? Trivia in different languages would have the advantage that significantly more people could play trivia. Especially the people. who do not speak the English language. Even people who speak the English language (not native speakers) can unfortunately often not answer the questions correctly due to unknown words. That would probably have an end.
If it is not possible to translate the trivia database into German, French, Spanish, etc. due to a lack of staff or something else, the community could do this.
It would also be logical to only pick out people who do not abuse the power they then have over your database. I realize that such people are not that easy to find, but still it should be feasible to find such people. To check the volunteers one could include the playing hours of the person, activity and penalties (bans etc.).
Of course, it is also logical that the person should at least be able to speak their own language (e.g. German).
