First of all, OrGoMan, this has nothing to do with competitiveness. This has to do with the fact that the personal statement is just that personal, and sharing it with someone I don't even know is akin to asking me about whether I'm a virgin or not--its just nobody's business but my own.
Second of all, the personal statement isn't intended as something to hold someone back, its purpose is to provide an impression for the reviewers of the applications. If this person truly wants to portray his/herself to an admissions committee as themselves, then the writing needs to be uniquely theirs, as well as the sentiments, ideas, and experiences in the statement. This is not to say that people won't have suggestions, but it is futile to write a personal statement that is truly your own unless you start it off before including the influence of anyone else. When I wrote mine, I just wrote, and then edited later.
Thirdly, calling names will get you nowhere.
And for the record, I have allowed people to borrow every single notebook of a class that they have requested. I have shared papers and essays with people for longer than you've probably been in school. And people who TRULY know me, know that I will tell them anything they want to know about anything, no holds barred. Be careful what you say to people because you never know who they are and who or what they know...
If the OP really wants examples of personal statements, try finding one of the many anthologies of personal statements out there that include statements from people who have already agreed to let people see their personal statement.
