Epic frown upon players who don't stick to the rules and play to beat others through cheating. An example would be 'individual' players who gang up and rush the unsuspecting player who's playing the game straight. Sadly some cheaters have been exploiting Battle Royale’s Solo mode by teaming up against individuals.
Now, it looks as if Epic Games will ban such offenders. There's a form you can fill in to report unfair behaviour. Try, https://epicgames.helpshift.com/a/fortnite. Always play fair yourself and the cheaters will get banned by Epic.
