Ahh another one of those reference links eh? Putting your Facebook on there means the chance that they post advertisements on your wall. Plus, using a free VPS isn't the best idea unless you want to host a simple web server. I get the idea that you are attempting to host a game server off that VPS. For that to be effective in anyway possible, you'd need to actually get a server that you pay for. Even then, a VPS wouldn't really be suitable for game servers, you'd need a dedicated server. But, again, it depends on the game. Some game servers don't need many resources.
