Content-wise, you may need to require a specific license for your app before publishing it on CafeBazaar, since social networks and blogs are not necessarily accurate. In cases where content accuracy is more essential, blogs or social media as a source is not valid and it might be needed to acquire certificates from specific resources. The certificate acquisition is the developer's responsibility. 

Here are some examples:

- Apps with the sensitive contents or sensitive information related to the user requires permission from the "center of development of information technology and digital media Ministry of Culture and Islamic Guidance".
- Apps with Live IRIB (Islamic Republic of Iran Broadcasting) services need to provide license for publishing.
- In some cases of horror games, the developer is required to get the necessary approvals from the "National Foundation of Computer Games".
