The Cult of Theta Discord is a community of gamers who are fans of Theta's work, although the Cult has now grown so much that the focus is often more on the regularly-scheduled lobbies, contests, and other events that are put on in the Cult.
One of the distinguishing features of the Cult is the rich inner culture that's been built out of it, as it is a veritable meme factory. From Accept Donut to Vietbon, the members of the Cult speak their own language and have created their own norms, transcending the standard (toxic) Discord culture found on many large servers.
In addition to Theta, there is a full staff of moderators and a strict code of conduct that is enforced to ensure that toxicity never takes over the Cult. It is considered one of the safest and most respected communities in the Onward/VR esports scene, and it continues to grow month-over-month.
