Check voat's homepage, and look how many upvotes do links have. It's dead, for the most part, although I guess very small communities (like those coming from /r/niggers, or /r/fatpeoplehate) are there to stay. But there is not much more to it.
Voat can have some good content in the sections for general gaming, tech, etc, since it's small enough that the spammers don't seem to be as common. That said, it's not really active enough to be anyone's primary social media/bookmarking platform, and that tends to mean that anything not super popular or controversial is pretty much completely dead there.
