Following concerns about the app's safety, harassment, nudity and incidents between minors and adults,[24][25][26][27] Yubo took various measures. Yubo entered into a partnership with Yoti in February 2019 to use their age estimation technology to analyze faces and estimate how old users are. The company claimed it has already checked more than 22 million profile pictures and removed a "few thousand" profiles belonging to under-13s as a result.[28][23] Safety advocates and governments have supported Yubo's efforts to place safeguards on the app, such as by creating a proactive "engage and educate" approach for their community, a mix between AI and human moderators, banning sexually explicit profile content and auto-blocking fake profiles.[29][30][31][32]
