From Blaseball Wiki

Glossip is a Blaseball news magazine released alongside every new season. It focuses on the personal lives and conflicts of players more than the sport itself, which makes it popular among casual viewers. Glossip is published completely anonymously, presumably to avoid the wrath of lawsuits from players and the ILB. Individuals seen distributing Glossip during games have been known to experience altercations with Rogue and Non-Rogue Umpires alike.
