This is the key issue it seems:
>As for the SignalR issues, I was able to confirm that Voat is running on a single box. Not a big deal given that it's still a hobby project for the developers, but the fact that it's not designed to run on anything other than a single box is an obvious problem. Either remove SignalR or support a backplane for it.
If that's all you have I think you can't afford to move quickly. You'd be looking at buying a server and managing it yourself.
AWS is really not cheap, it's quite expensive to just 'scale'.
Shame on you for speading such FUD. Where is kiddie porn on voat ?
Not five hours later, those “sexually oriented materials” came to light on Voat’s front page: Many of the girls pictured nude in the site’s “jailbait” forum, one user observed, are clearly underage."
