The red flags I noticed before that bugged me were the total lack of open source and the logo contest. And one other thing that I haven't seen mentioned yet which was I always seemed to have inflated viewer numbers.

When I steam on twitch "Factorio" which is a nice indie game (in beta) but it's not popular like PUBG or Fortnight or LoL are. I get maybe 3 viewers (usually just 1 or 2 or even 0). However if I do have a couple viewers they almost always will chat. When I streamed on DLive I'd always have 10 to 20 viewers, but no one ever said a thing. It was like they weren't really people there. I'm convinced now that they weren't. It was just inflated numbers to make me feel better and stay around, since it is all closed source who knows how they were coming up with those stats.
