Sounds like you need a new account with a clean history. The best way is to find someone who doesn't sell isk on sites like that and to do individual transactions with them. You will end up paying more for your isk, but it will come with significantly less risk. If you have the uprfront money you can wait for one of the 20k plex sales where you can get isk for around 6$USD/1b isk through CCP themselves. Those are really your only options if you dont want to risk getting axed.
