There could be several reasons why your post was not approved or taken down:

Scenario 1: The promotional content of your post contained inaccurate information or violated the platform’s promotion guidelines. Common issues include promoting special industries that are not suitable for commercial promotion according to legal regulations (such as insurance, securities, credit, tobacco, firearms, and prescription drugs), and damaging the rights and interests of the platform, merchants, and other participants. Your promotional content must comply with the contract terms outlined in the KOC Agreement

Scenario 2: If all the products associated with the Post are sold out, your friends and followers will no longer be able to make additional purchases through the Post. As a result, the Post will be automatically taken down from the community display. However, you can still see past Posts in the “Account” section. Once the products are back in stock, you can edit and reapply to publish the Post, or you can choose to promote different products.
