Did you seriously come back and jump right into making requests again? Isn't this what earned you the -9 rep you currently have and your eventual departure form the site the first time around. You really may want to rethink this a bit.

What can I do to change my reputation?

To get people to raise your reputation, make meaningful and thought out posts, be kind to others and associate with others. Though you should remember that rep is just a number/stat on the site, and doesn't have to represent who you are.
