Activity is bad. We can't moderate everyone, and there are so many 12 year olds here that it;s a problem.
The wiki isn't "Dying", so much as just going through a cycle of activity that leads to a negative feedback loop. Once it becomes overwhelming, the wiki will go to shit, people will leave, then it'll be small enough to fix. Then people will start coming back.
I think the only way to stop this negative feedback loop is to ban literally everyone who puts low quality anything on the website but that's not happening
