What to do against Streamsniper Fortnite?

I've been streaming Fortnite (Custom Games, Skin Contest, etc.) on YouTube almost every day since the beginning of February.

Already have 908 subscriptions. Only 2 former friends don't allow me to do it and streamsnip every round. Is then also really demoing.

Can I write an email to EPIC GAMES? Always report them, but unfortunately nothing happens. Or do you have ideas what could be done?

Stream delay is the only option.
