I am in the "Don't argue with them, it makes them stay longer." and the "Ignore them or kill them with kindness/jokes/cute emotes." camp.
Usually when the griefers realise that you're not as bothered by them as they want you to be, they leave you alone. The others will actually start feeling bad about harassing you if you're nice enough.Â
The fastest way to make a griefer stick is by arguing with them or trying to shame them for trolling you. As Bryn said, the second you complain, they won. They want the negative backlash from you.
