"When a new season kicks off, all Fortnite's player levels get reset and even the most experienced players encounter bots in the first matches. The number of bots you'll see in your games will decrease since the game can tell you're getting better, and you'll start getting in lobbies with almost no bots."

But watching this video you should immediately get some ideas for detection of bots/cheats - tracking player visibility, gaze and movement behavior server side. Someone consistently "spotting" enemies 600m away in a building, reacting to silent entities being spawned behind them, head/eyes shots thru foliage, etc.
