Question on entering a contest without a name identifier.

Hello, I am new to entering contests on Poetry Soup.   I hope you can help with this question that puzzles me.  Most contests state that you should submit a new poem in your Member Area without your name.  I assume that the sponsor doesn't want to know the name so it won't prejudice his/her opinion.  However if you post the poem in your member area, it seems that it would be difficult to keep your name separate from the poem that you entered?  Are there some ways that this is handled that I'm not aware of?  Thanks, Kathy
