Agora is down because it's a terribly unreliable website. It goes down all the fucking time. As it is there's no evidence that there's a scam or anything. Don't listen to these morons.
Edit: For those who didn't see his original post, aktophot claimed that he was connected with Agora's team and knew that they were scammed. However, nobody has any actual evidence of anything of the sort.
I feel like Retard Warnings should be accompanied by this video, and become a common thing on this sub.
