In recent months players have been submitting an average of one million questions a day to Trivia Crack’s “Question Factory,” a section within the app, says its 29-year-old founder and chief executive, Maximo Cavazzani. Since each submission must get a positive rating from at least 100 fellow players to make the cut, only about 1,500 new questions are being added to the game each day.

I played Ingress for a while last year. I am still getting responses about portals accepted or rejected, and I have at least 50 more in their queue. Back then, the Ingress web site said portals were accepted or rejected in 4-6 weeks (not months); right now it says that due to the backlog they have suspended the achievement related to submitting portals (and also quietly removed a turnaround time).
I have wondered if the time delay is an intentional strategy to reduce exploits. If the average player quits before their submitted portals go live, there is less incentive to submit dodgy “couch portals” (portal you can reach from home/work).
