can adwords see your mac address

Hi, I am working on getting multiple adwords accounts and in other threads I see conflicting opinions on whether adwords can see your mac address or not. So is this something I need to change or not? thank you!

my current plan on the mult. google accounts if you would care to comment as well is:

change ip
clear cookies and flash cookies
no google toolbar/gmail/adwords editor
different names/emails/credit cards & addresses

anyone who is running mult accounts right now pm me out of the goodness of your heart or I'm a ppv/ppc person if you can help me I can trade pointers.

Yes, they CAN see your mac address. And they also can see from what ip you're accesing your account, so be very carefull.
