I did want to chalk it up to it being a coincidence. We all get spam emails from time to time. But i've had my email for 20+ years now and the sheer amount of spam is well past 200+ which has never happened.
And the request for an email for custom forms was odd from the jump. As citizen I don't know what it's like to travel to the states as a non-citizen but is it ever asked for?
Maybe it's a coincidence.
