Multiple adsense accounts - How?

I want to know how people have multiple adsense accounts. I hear this all the time, but am not sure how to implement it. Sure, family members is one method. For this - does it matter if adsense is accessed using same IP ? Or registered on same address?

Other than that, what's the other method? LLC is what I hear a lot, but I am in Canada - anyone the Canadian equivalent method?

Thanks, really appreciate your help.

This is just so I can spread my websites across various accounts and be more safe in the long run.

You can form a foreign-owned LLC in the united states.

Plenty of companies out there offer this service, a quick google will turn up plenty.

So how does LLC actually work? You register on your name but different LLC each time?
And what about IP. Is it risky to access multiple accounts from same IP? If so, do you use a proxy for all accounts?

Some input please.

Forget forming a LLC. You can be a sole proprietor and save on the costs of forming an entity. You can declare yourself to be running one or more businesses anytime you want. Just get a unique EIN number from the IRS for free to distinguish the businesses in Google's eyes.

I know a lot of people here have multiple adsense accounts and manage various sites on them. I really want to know how they do it - do they access accounts using different IPs , etc? Some details please guys, will really help me!

Thanks
