I run one at the moment. In the past, I noticed I could only get one or two per computer. I think Amazon tracks more than the IP. Google does the same thing.
No "I think" about it - Amazon tracks a ton of info including browser fingerprinting

Amazon definitely tracks the MAC.
I didn't think about browser fingerprinting, that's new one for me. I guess it might be a good idea to get different versions of mozilla!
Form SS-4 has to be filled out with your real, actual, bona fide information. That's the form you fill out to get an EIN. Although, no one can see who has the EIN except the IRS. Start a DBA, get a tax ID, and you're doing business under a new identity... legally.
So Amazon does not check your name that you provided with the IRS? Why bother with the DBA then? Why not get the IEN and give Amazon a different name?
