Solve Issues with Admob --1

Hi, I have created multiple android apps and used AdMob for Advertising. It worked for 2-3 days and then my AdMob account got blocked for either "limited ads" or "account being accessed" or "Invalid traffic concerns". I want someone to guide me on this. I have got 3 of my Google accounts wasted till now. Please bid if you have solved such issue before. Start your bid with word expert so that I can know that you have read the full description. Thanks
