I tried searching for Voat via Google search. There was the Wikipedia link, subreddit, and articles about Voat, but no link to the actual site. I thought something may have happened to the robot.txt document, but I searched via DuckDuckGo and Yahoo and found it first entry. Obvious censorship.
Edit: It was second listing as of yesterday.

Edit3: As of 2:34PM it is back up at #2 https://kek.gg/i/7M7gp.png I don't know what bullshittery is going on.
