So I've made a new account on amazon on a Tor browser (new IP I hope) to hopefully avoid amazon linking my accounts and SEs...
Though as I was about to buy airpods, it stated that on delivery I'll need to verify by saying my OTP from my emails.
Does this mean they've flagged every account or is it random?
I was planning to do an EB on these airpods but if they can see my previous purchases on my other accounts then I don't want to risk it.

so is the OTP random or due to malicious activity?
