Wu became a target of Gamergate harassment after posting a tweet criticizing misogyny in the gaming community. This marked the beginning of intense and sustained online abuse.

Wu received numerous death threats, doxing, and other forms of online harassment, forcing her and her husband to flee their home and live in hiding.

Despite the severe harassment, Wu remained a vocal critic of Gamergate and a staunch advocate for online safety, diversity, and inclusion in gaming. She has spoken publicly about her experiences and worked to raise awareness of the issue.

Following Gamergate, Wu has continued to be a prominent voice in discussions surrounding online harassment and abuse. She has advocated for stricter moderation policies on social media platforms and worked to support other victims of online harassment.
