Nicolas Demario bit Josue Vargas during their super lightweight boxing match in Las Vegas

I meant to already bring this up because I've not seen a thread started about it. I wanna know what are the fans thoughts on this behavior. I personally love our sport and understand their is a certain level of dirty tactics and honestly dont put much stock into because dirty tactics are part of every sport. However things like biting I believe should be automatic DQ and a fine that goes to the fighter that was bit. There certain flagrant fouls that are inexcusable. If a fighter throws an intended elbow or intentionally throws a headbutt and I mean intentionally throws one not a clash of heads or bites another fighter or even purposely c o c k shots a fighter its flagrant. I know some of these examples are hard to prove as intentionally done but with replay and circumstances it's not impossible to show intent. What are others thoughts? I for one absolutely love a hard nose rough and tough fight but there are limits on how far it should go and still be excused.
