<P> Dent and Nickson sparked backlash after footage of remarks regarded as transphobic was depicted on the live feeds . During a conversation in the hot tub, Graf informed Dent and Nickson about Audrey Middleton of Big Brother 17 as the first transgender contestant in the show's history . Nickson proceeded to mock the gender identity of Middleton, for whom Dent was also confused about the appropriate pronoun . Middleton addressed the controversy through a Twitter post, urging people not to vilify both male HouseGuests but rather, educate them on the value of emotional intelligence . Nickson was also criticized for using the derogatory term "tranny" several times earlier in the game . </P> <P> Fans were heavily divided on the authenticity of some of Walton's claims in the House . As a gastroparesis (GP) sufferer, Walton often commented that her gastric pacemaker was burdensome, that her condition was hereditary and terminal, and that she was sterile, making her consider egg - freezing, hysterectomy, and knee surgery before her death . Even before joining the show, Walton had established a $200,000 campaign on GoFundMe for her treatment, which some skeptical fans considered a scam . Schlehuber also recounted Walton asking viewers for money on camera . Other GP sufferers and organizations like Gastroparesis Patient Association for Cures and Treatment disputed her claims about the severity of the disease . However, Walton's mother, Stacy, and her physician, Dr. Thomas Abell, took it to social media to combat Walton's critics, even stating "there's basically many different ways to die from gastroparesis ..." Fans also accused Walton of being an "attention seeker" or having hypochondria or Munchausen syndrome due to her allegedly exaggerating other health conditions and lying about having GP based on her unhealthy eating habits in the House . Walton also claimed that she and her mother were members of Mensa International but their names were proven not to be found in the organization's current directory . </P> <P> Several HouseGuests, especially Graf, attracted controversy for engaging in a certain inappropriate behavior in the House . Footage on the live feeds showed Graf making unwanted contact with some HouseGuests in their "private areas" in a joking manner without prior consent . When confronted, Graf dismissed any accusations of such wrongdoing as sexual harassment or invasion of privacy . Ironically, Graf's behavior incited other HouseGuests like Abrahamian, Matthew Clines, Ramses Soto, and Elena Davies to partake in similar playful acts towards HouseGuests of the same and opposite genders . In one episode of the show, Ow shared with Martinez how the rampant "touching" in the House, particularly her experience with Graf, made her uncomfortable because it was reminiscent of her cousin who had been raped and murdered . </P> <Table> <Tr> <Th> #</Th> <Th> Air Date </Th> <Th_colspan="4"> United States </Th> <Th> Source </Th> </Tr> <Tr> <Th> 18--49 (rating / share) </Th> <Th> Viewers
