Both are.
However, you can have multiple official accounts which you can use to guide your users. But you have to be under one announcement thread. I saw you launched a signature campaign. Good luck with your business.
This suggestion has been given to them right from the very moment they launched the second Ann but seems like they are making use of the both thread for announcement. I think they needs reputable manager to guide them through how the forum works to avoid restrictions and limitations, if instructions are not adhered there could calls for much restrictions.
