Grok users say an alarming CSAM block message appeared out of nowhere, then quietly changed

A batch of Grok users started finding their accounts locked a few days ago with a message nobody wants to see. The block screen named NCMEC, the National Center for Missing & Exploited Children, and cited CSAM. Getting that on your screen when you’re just trying to log in is pretty alarming, even if you’ve done nothing wrong.

After digging into the r/grok subreddit, it seems that reports about this started stacking up 3-4 days ago. Several affected users say they never touched Grok Imagine, let alone generated anything illegal.

One example that came was a user who uploaded a family photo and asked Grok to remove the kids from the image. That apparently tripped the filter.

As of today, xAI seems to have quietly pulled the NCMEC and CSAM wording from the message. Multiple users now report seeing a plain “User is blocked” or just a moderation notice instead, like the authentication failure screen a user shared on Reddit.

xAI hasn’t said anything publicly about any of this. One user who emailed [email protected] is sitting on three-plus days without a response. One SuperGrok annual subscriber says they can’t even cancel their plan because they can’t get into the account.

The most likely explanation going around is that xAI’s automated safety filters over-fired. US platforms are legally required to report suspected CSAM to NCMEC, and the hash-matching tools used to scan for it can produce false positives, especially with AI-generated content. Swapping in a neutral “User is blocked” at least stops the original message from wrongly tainting innocent accounts, even if the block itself stays in place.

Grok has been having a rough run on the moderation front. NSFW settings vanished without explanation in March, Grok Imagine users had generated videos wiped without warning around the same period, and the platform spent much of late 2025 and early 2026 under fire after it was being used to undress women in public X threads. Even Elon Musk publicly took aim at his own platform’s overmoderation back in January.

That said, xAI has yet to issue any formal statement about these sudden block notices. We’ll keep an eye out for any further developments and will update the article accordingly.
