Im not the famous in-game either yet, but I think I know some ways to get noticed more.
Make an interesting group! Try and get a lot of people to join
Get involved in what people are doing! Join in conversations, get to know people, things like that!
Something that gets me, and probably a lot of other people noticed is making a Youtube account using the same username that you use in game. Make funny videos of FH, then people will know you more!
Another thing you could try is talking in General. I know, I know, sounds stupid. Right? Well, thats how I made two best friends in game :3
Anyway, I tried to help the best I could. Sorry if it didn't :3
