Negative Votes?

How can you have negative votes? This girl, *angelofdeath* has -11. I'm confused... It looks like she deleated some of her poems but still, how can you be in the negatives?

Here is her profile:

Yea, and also it says she wrote 24 poems (which she did, she probably deleated them) and she only has one.
