I knew this would happen and that's why I am FOR hardcoded community limits per user unless an admin, in individual cases, allows the user to open additional communities based on past handling of other communities the user has been (or was supposed to be) modding.
Letting a user create 54 communities, especially those that were some of the biggest communities on Reddit is dangerous. Powermodding is a serious problem on online platforms and letting individual users create unlimited communities leads to it. Imagine how much money this person might want to sell their Account(s) for when the platform grows further and interest might accrue?
It is humanely impossible to mod more than a handful of communities alone anyways. The users you mentioned are powermods.
As another good example against freedom of creating unlimited communities is user LMAO whom most of you will probably at least have heard of by now, or even found when searching for a community that has numbers in its name.
I will stand by this position.
