On October 29, 2025, during Tanzania's general election, security forces cracked down on protests, leading to reports of hundreds killed according to the UN and rights groups, though the government disputes the figures. Kimambi shared screenshots of Meta disabling her personal account and WhatsApp number +1-424-537-3057, which she links to her posts about the unrest and evidence received from citizens. Separately, activist Maria Sarungi-Tsehai's Instagram was restricted in Tanzania at the communications regulator's request. Kimambi vows to keep advocating for peaceful protests ahead of December 9 amid ongoing arrests and international scrutiny.
