Weird things on Craig's List

While I was uploading some large files I came across these two items on the "Women Seeking Men" section

Item One:

Hi. I am staying with friends outside Buckhead, BUt I have to move..I am 25 former Bad girl (was in trouble, not now)single. Looking to move in and COOK CLEAN DO LAUNDRY AND TAKE CARE OF YOUR NEEDS in xchange for rent and....I am very good looking..5'6" 111 lt brown hair green eyes. and for real...Race doesnt matter

Item Two:

I am seeking a professional man that owns his own business and calls all the shots. To describe my self a little, I am multi-ethnic, 5'5, 130lbs, carmel skin, white teeth, nice curly medium length hair, very intelligent, discrete and sweet.

I'm seeking employment, something 40 hours a weeks( I have a resume)
The beneifits are office sex with me, or a side relationship.
If you are serious respond with a place where we can interview(not a hotel or a house)and a job details.

I'm not sure which combination of sued/murdered/robbed/conned would result, but at least two of them seem certain. Does people post these things because they work, or is it just a cry of desperation?
