The process to integrate Facebook into Sether takes some time. Our application is finished and under approval. Due to the recent media uproar, Facebook is reviewing its API integration rules and it will probably take longer for this alignment to happen. This means that registering on Sether with your Facebook account and holding Facebook influencer campaigns are currently unavailable. Sether 1.0 Beta only allows Twitter for campaigns and influencer registration.
Sether 1.0 – the next release – will offer integration with owned media, Reddit, Instagram, Telegram, Bitcointalk and, of course, Facebook.
