Alexis? He worked at Whiskey Media (GB's previous parent company), and then at CBSi until he left for Twitch. He was never technically employed at GB, but by Whiskey Media and then CBSi as a designer (but he was in a bunch of content). The "employees" section of the Wikipedia article is pretty inaccurate since neither Dave Snider, Ian Kelly, Alexis or Rorie have ever been employed by GB, but always by the parent company directly. To say that Ian was employed by GB is like saying that Andy Bauman is employed by GB right now.
Also, Ryan had a Wikipedia article for a long time, but it got taken down because it didn't contain enough information. I'm guessing it has something to do with Wikipedia's different requirements for articles about living people and people who have passed away.
