WhatsApp Business, under the latest policies (January), is banning accounts that use TextBlaze, as it considers this non-human behavior and spam (even if it isn’t). Please be careful or take precautions.
Do you have any additional information about this? WhatsApp is looking to put an end to apps that automate these tasks.
Can you share the policies you are referring to? I couldn't find them.
In general, websites may take action against behavior they view as spam-like. You should make sure your usage of WhatsApp isn't something that could be viewed as spamming. If it does, your account could be banned, whether or not you are using Text Blaze.
