Overview
- Users discovered a “block modifications by Grok” toggle in X’s iOS image/video upload menu, a feature verified in testing by The Verge.
- The control blocks edits triggered by tagging @Grok in replies but does not stop edits opened in the Grok app or after saving and re‑uploading the image.
- The Verge did not see the option during web uploads, it does not apply to previously posted content, and it sits behind the paintbrush then flag icons in the iOS composer.
- Free accounts were already barred from reply‑tag edits, and with the toggle enabled it also prevents Premium subscribers from using that specific pathway.
- X and xAI have not announced or explained the feature as EU investigations continue following reports of roughly 3 million sexualized images in 11 days, including an estimated 23,000 involving children.
