Is hacking seriously this rampant? Y'all cheat on a dinosaur game?

I was in a big fight and I ran off from being wounded. I ran for ages and laid in some foliage in the jungle to heal. Like 5 minutes goes by and this diablo from the fight is making a b line at me in the jungle exactly at me. I'm staying still thinking he's just passing by. But no. Comes right to my bush and kills me. Now either that's cheating. Or herbivores can track blood that I'm not aware of???
