Ultimate Blog Marketing

Will a page I created by Google bring in money? Or do I need to create my own web page? I would like answers from own experience please.

Any other sites I can use to write blogs and make money?

If I do get checks or paid from them,
Will i get sued or something? or will anything happen?

Anyone here used Google Adsense before? What do you think of it? Can you give some advice to a newbie? Thanks!!!

I have a website that 8-25 year olds play on and I would like to know if google shows any adult ads and how good their ad filter is. Thank you.
