"she said she could have done even better but she's been under a lot of stress over the past few days because of the accusations. She also wore a mask during her appearance on the stream to hide her identity, which all by itself is a tremendously sad comment on the state of videogaming."
Chalk does not appear to consider the possibility of stress might mean that someone could have caught a cold. It is common in asian nations to wear procedure masks to protect others from your germs.
Even if she was not sick, she might be worried about catching a cold due to lowered immune system from stress, since many people were in the place watching her and could have spread germs.

"Inven hosted a livestream of Geguri so she could further clear her name for those who still didn’t believe she wasn’t cheating. The site also noted that the reaction against her certainly seemed due to discrimination"
This is vague and does not specify if the Inven site claims specified age or gender or some other discrimination. It also does not link to its source for us to read, or say who on Inven said that.
Nor does it say the basis for assuming discrimination is the reason for the doubt of her skills.
