Ciara (correctly spelled Cierra Ortega) left the reality show "Love Island USA" because she was asked to leave the villa due to past racist comments that resurfaced on her social media. The show's producers stated that she broke some of the policies or guidelines, leading to her removal. Specifically, two social media posts containing racial slurs offensive to Asian people came to light, which caused controversy and backlash. Cierra and her family later issued statements acknowledging the situation, with Cierra posting an accountability video expressing remorse and explaining she did not fully understand the harm caused by her words. Despite the backlash, her family asked for compassion against the hate she received after the incident became public. Her departure was described officially as due to a "personal situation," but it was tied to the controversy over these posts. In summary, Cierra left because past offensive social media posts surfaced, violating the show's guidelines and leading to her being removed from the villa.
