How does Kagi know if multiple users are on the same plan if there are no search/IP logging systems?

You do have to login to your account. And they know which accounts are linked together on a bill.
Maybe I don't understand the question.
- What prevents one account from being used by multiple people?
  
  Alternatively, I have 3 computers, a phone, and a tablet. What prevents Kagi from banning me for sharing my account even though all of the devices are mine and I’m the only one using them?
