If there are 2 accounts under the same name and surname but totally different shipping address (not a typo in) then it's sufficient.

Are you serious? This gives them all the more reason to check.

If they cross-check both accounts, and Identify the payment system, device, IP address and so forth are the same, then there's obviously an association between both.

They can't link them unless they find other kinds of connection IP, browser signature, etc...

That's my point by stating "change every Identifiable detail"- they do link accounts with the above Information.

Perhaps I express myself wrongly, I am saying that during a check they might think that 2 accounts with same name and surname but different shipping addresses might be owned by the same person, However they can't link them unless they have more identical details between such as (IP, Card used, browser signature etc).
Otherwise for example, all the "William Smith" in a nation would be the identical person for Amazon and it's not...

This is what I'm saying.
