What does "This group is no longer available" mean?

WhatsApp uses advanced machine learning technology to evaluate group information including group subjects, profile photos, and group descriptions. We also provide simple options for users to make reports to us from any chat. We may prevent further activity in chat groups to comply with our legal obligations. We may also prevent further chat activity when a group admin is in violation of our Terms of Service.
For additional help, please contact our WhatsApp Support team.
