Let's be real, why are simon says servers and grill and chill servers banned? It makes no sense on why they're banned outside of "mass teaming" and "ruining other peoples fun." If you're entering a server like that, you're willingly and knowingly entering into a server that is designed for gameplay outside of killing. Besides illegal farming in public servers (zombies surrendering without attacking, otherwise, kicked), the rule makes no sense.
Also, it's the person's VIP server. Let them do what they want as long as it's not malicious.
