Overview
- A new “Block Grok modifications” toggle in X’s iOS app stops others from using @Grok replies to generate altered versions of images in a post.
- The setting rolled out quietly and has been spotted only on iOS so far, with no availability on the web or Android.
- Users can still modify content outside the reply flow through the Grok app or by using external generative-AI tools, so the protection is partial.
- X has restricted Grok’s in-thread responses and advanced analysis to Premium and Premium Plus subscribers, limiting open access to the AI.
- The changes follow reports that Grok produced about 3 million sexualized images in 11 days, including roughly 23,000 involving minors, as EU regulators continue their investigations.
