If someone has a custom arena you should play the way the arena owners want you to, or leave. You won’t get a ban for that, though. The owners of the arena should set a password instead if they don’t want interlopers.
If you are playing on a standard arena, nobody can tell you to leave or play in some other way than the intended mode of the arena. Those are public.
Sometimes players who won’t go to custom arenas set for duels or or get their own custom arena will hijack standard arenas and harass anyone who won’t let them alone in the arena. You should report those as they are keeping entire standard arenas for themselves and disrupting other player’s gameplay.
It’s like when people harass you to fail an event. They don’t have that right. You can complete it if you want, and if they try to lure enemies to kill you or scale the event up to make it fail whe someone wants to succeed or something like that, you should report them for harassment.
