1 death threat, 2 boxing challenge threats
Thats not a cool thing to do, but thats really means nothing at all, do not represent any risk. Intimidation is part of the Brazilian culture of cheering in all sports, as well as many other countries: Argentina, Uruguai, Turkey...
In the Blast Pro Series São Paulo the crowd was yelling " UH VAI MORRER!" to astralis team and guess what? no body got hurted, not even close to that. The point is people are overreacting. If this little poor 16 yo (who's cheating IMO) can't handle the pression, so please go call his parents, because he should not even be on twitter.
