You say you get infractions/warnings for useless posts? Well that's an obvious fix mate, put more thought in to what you are going to say. This isn't a fast-timed instant messaging place, you can take your time to think out something. <-- This is one of the first steps to get popular or be helpful.
Staff and players don't hold grudges, believe me, you will get known. Just join a clan and find some organisations. If you are having trouble with writing an application for them, just take your time and have a breath, google is always there for you.
I hope you don't give up here mate, as you can recover quite easily. Good luck.
