I'm not sure how /v works on other servers, but for Olympus, MVP+ don't have it. It can only be won from a perk crate, which you can buy the keys for on the store, or at the moment, win in the Christmas chest. I agree, there's not much point in players having it, as there's no real use, besides hiding from in-game commands. I suppose it stops people from messaging you, which in some cases can be useful if a player won't stop messaging you.
