From Blaseball Wiki
Suggestions for places Malik is banned from.
Akihabara district in Tokyo: Predictive modelling suggest that the riots caused by even the knowledge, much less the presence of an actual Catboy there would cost somewhere in the area of 13 billion Yen.
The parking lot of the McDonald's on 3rd avenue on Pine Street: Keeps fighting with a feral Maine Coon over an unopened tin of tuna from the 1970's. This is in spite of the fact that even with opposable thumbs, Malik is still somehow incapable of opening any canned food.
The Core: Malik considers it a "roguelike dungeon", and won't read the Manual, much less follow D.O.W.N. safety regulations. They're allowed to play at the Pillars still, thanks to its accessible, un-Down location.
