If I am a professional in something, why not use Fluther to promote my business by using my real name as a user name?

Just out of curiosity, I have never seen a professional user using his real name to promote himself as a professional in something, any subject. But, I saw it in other web sites. If I was a doctor and would like to get more patients I probably use Fluther with my real name (Dr. Oz, anyone?) and it may help my work life. Is it forbidden? Is it good or bad for that person?

There are lots of people who use social networking to promot their work
