will google ban you if you login to your adsense account from the same ip as a person that is working in the same company as you?
me and my brother are using adsense from the same for last one year. We have not faced any problem yet and i think if they ask i can explain them that we are two different persons having different domains and would be separate in coming years as well
The only risk you run is if the other people in your company are clicking your ads. What you may want to do is hide ads on your pages for visitors from your work ip.
