Overview
- Hundreds to thousands of users reported sudden blocks that showed an in-app notice stating accounts were “under analysis” and that results would arrive within 24 hours, according to social posts and monitoring site reports.
- The surge of complaints was first widely reported on Monday and tracking service DownDetector logged spikes in reports through the day, with peaks in the late afternoon and evening.
- Blocked accounts could not send messages or use normal app functions during review, and many affected people said they had not broken WhatsApp rules.
- Meta issued a brief statement saying it bans accounts to prevent misuse, acknowledged mistakes can happen, and said it will seek to resolve erroneous blocks but did not disclose how many accounts were affected or the technical cause.
- Industry observers suggested possible causes such as spam-filter thresholds, a software bug, or interactions with a recent username rollout, and users are advised to request in-app reviews and use Meta’s official business APIs if they rely on automation.
