I don't think we should discourage good writers, who accept NPOV and adhere to it, from editing their own articles. I encouraged free software pioneer Richard Stallman to edit [[Richard Stallman]], after painstakingly confirming his identity by phone and e-mail. He hasn't gotten involved in edit wars or tried to censor negative POVs about himself, has he?
I spent many hours of my time, helping controversial physicist Jack Sarfatti to learn our ways. After a false start or two, he has managed to avoid being banned again and has even stayed out of edit wars.
There is no reason to make notable people write autobiography anonymously, provided (as Fred suggests) they DON'T "begin intensive editing in order to remove negative information or add positive information". When you look at the history or the diff, you'll see that Stallman wrote "in Java" - meaning that he developed software while on the Island of Java in Indonesia! And why shouldn't the source for this bit of programming trivia be Stallman himself?
