Few hours? More like few seconds. I know it's a movie made for 13 year olds but if there were actually an MMO that basically every young adult was playing 24/7, they would figure out all the secrets in an instant. Have you SEEN how quickly people solve ARGs? Usually developers have to slowly drip information or else everyone will crack the extremely difficult hidden code within an hour or something.
Seriously, we have people beating Dark Souls with a guitar hero controller and running a game for over a month to make it crash, hard to believe people hadn't figured out how to clip through the course entirely.
Over the last several years, WoW has been getting some secrets that have taken months, sometimes over a year to be completely solved. There is a Discord server dedicated to solving them, and it's hit the max member limit a few times.
Although, most of the secrets have just the slightest hint that they even exist.
