SO9 posts through the platform's official API. You can watch the video below to understand more about how SO9 works: Watch video

However, if you want to use a proxy, open SO9 in a browser with a proxy enabled when connecting accounts or channels. After connecting successfully, you can use SO9 in any browser.

If you're using a proxy or fixed IP for managing accounts, keep that setup when connecting them to SO9.

Note: If a customer is using a phone box, guide them to use Chrome on that phone to connect their channel to SO9.

The reupload feature uploads the original video without editing. There are two common approaches:

1. Use third-party tools (e.g., Eric or DHB) to bulk download and edit videos, then use SO9’s bulk posting feature to schedule and manage them.
2. Direct reupload: Many users reupload directly. Editing helps avoid copyright, but it’s not foolproof. Major channels may still trigger copyright strikes. Facebook’s current system is less strict, often targeting VIA accounts, not Fanpages. Also, RM (copyright detection) tools are less active in Vietnam, making direct reuploads viable.
