The mod for that game hasn't been on in 9 days, you can try contacting them through twitter or discord, if you don't get any sort of response or acceptance and the mod still doesn't log on for several weeks then you can try to request for mod

Having the world record/it being your main game aren't enough to make you mod. However if the current mod never replies to you/does anything about it then you would have a good chance at becoming mod. :D
