> The GME centered group left WSB because there was a new mod who didn't fit the WSB philosophy. There were some personal hypothesis about her(?). They even alleged I believe that mod made their adolescent child a mod of WSB who were also removing content left and right.

You are confused. This has nothing to do with WSB.

What you are describing happened solely on r/SuperStonk or the other GME subreddits.

WSB has never had a child moderator.
