I would advise caution when it comes to buying access to the Facebook Media Partner Portal. Access to the portal is typically granted to authorized media partners who have established relationships with Facebook. Purchasing access from a third party could potentially violate Facebook's terms of service and put your account at risk of suspension or termination.
If you are looking to become a Facebook media partner, I recommend reaching out to Facebook directly to inquire about the requirements and application process. Building a legitimate partnership with Facebook will ensure that you have access to the necessary resources and support for your media activities.
It's important to prioritize transparency and compliance with platform policies to maintain a positive and sustainable relationship with Facebook. If you have any more questions or need further guidance on this topic, feel free to ask.
