I think people don't like him because he has a big ego and apparently he's toxic in ranked, I don't know much about him so other Brazilians can give more details, but is undeniable that he is one of the best players in Brazil.

I dont follow him too much, but its because his personality I think, but in the end is just jealousy, many people like him too, he is a good guy and play very well

I've been following xand since the counter strike, and I can say he's a good person. But it's a little toxic in the rankings and ends up suffering a lot of hater from the community, especially when it doesn't have a good performance.
