We are aware that some users are encountering a Scripted account detected by scaled actor detection systems error on Facebook. Our engineers have investigated the error and found this to be an issue on Facebook's end.
Based on someone's account activity, Facebook seems to be restricting or suspending certain accounts from streaming. Unfortunately, the restriction is entirely on Facebook's side—StreamYard would not have control to lift it. Facebook may instate restrictions/bans due to community guidelines violations, copyright strikes, or activity they determine to be suspicious.
We've reached out to Facebook to report the problem. In the meantime, we recommend appealing any suspensions you believe to be wrongly placed on Facebook's end here.
