Not really.
You can look in My Contributions to the left in the blue toolbar. It will show you every contribution you have made to WikiAnswers since you registered. From there, you can visit each question that you answered by promoting yourself or your business or service and remove that information. If you promoted by using links on questions, you can also remove those.
First of all, they're called TRUST points. When someone answers/edits a question, scroll down and hit "recommend user". You can only recommend a user once. You can also recommend yourself... Once!

The numbers beside the usernames are Trust Points. Trust Points are points given by other contributors who think a contributor has done an outstanding job on WikiAnswers. The amount of points is the amount of people who trust you and your contributions. There should be a 'recommend' button by your name if you made the last edit in an answer. You can recommend yourself once. To advance your Trust Points, just make high-quality answers and/or contributions to WikiAnswers and someone is bound to trust you.
Yes, after all, if you can't trust yourself, how can others trust you?
WikiAnswers has so many members because Wikianswers is a great site to ask your questions and get them answered [by real people], or answer a question yourself. So, why not join the WikiAnswers Community today?
You CAN. But it's extremely unlikely.
