Your WhatsApp account can be temporarily blocked if you violate the rules set by the messaging app owned by Meta. When this happens, you won't be able to use it to send messages or access other features.
Upon opening WhatsApp that has been temporarily blocked, users will see a message stating "This account is not allowed to use WhatsApp."
Quoting the WhatsApp Help Center, they will block an account if they believe there is activity that violates the Terms of Service.
If you receive a message in the app stating that your account has been temporarily blocked, it means you have violated rules such as the following:
Using Unauthorized WhatsApp Apps
Unauthorized WhatsApp apps can compromise the security and safety of users.
Several things can happen if you use unauthorized WhatsApp apps:
There is no guarantee that messages, data, location, or files you share will be private and secure.
Your account may be blocked for using unauthorized WhatsApp apps, which goes against the Terms of Service.
To ensure you have access to WhatsApp, confirm your number again in the official WhatsApp app. You can download the app from www.whatsapp.com/download.
Engaging in Information Gathering, Also Known as Scraping
Scraping is the automatic extraction, either targeted or on a large scale, for unauthorized purposes.
Obtaining user information in this way, including phone numbers, user profile pictures, and statuses, violates the WhatsApp Terms of Service.
Some accounts may be temporarily or permanently blocked if they are suspected of scraping personal information from the WhatsApp app.
Being Evaluated for Spamming
WhatsApp temporary blocks can still occur even if users use the official WhatsApp app.
Another reason for temporary WhatsApp blocking is when users are deemed to be spamming, engaging in fraud, or engaging in activities that endanger the security of other users.
How to Resolve a Temporary WhatsApp Block
When an account is blocked for violating rules, you can tap on "Request Review" in the app, and WhatsApp will review your report.
Requesting a review can be done through the following link: https://www.whatsapp.com/contact/?subject=messenger
You can also contact WhatsApp directly from your phone by opening WhatsApp > Settings > Help > Contact Us.
"We will contact you as soon as we complete the review," WhatsApp writes on their website.
The company advises users to review the "Permitted Use of Our Services" section of the Terms of Service to learn more about proper WhatsApp usage and what activities violate the Terms of Service.
