It's not likely that. The US government, like many other countries, is using facial recognition at the border. His face pics used to be unblurred on RM so they are likely in the database. That has been discussed in the forum a few times. That likely got him flagged for secondary screening. It was the messages with clients on his phone that confirmed to them that he was going to engage in prostitution.
He might have avoided it by carrying a burner phone and reloading his apps later. But being in the database really hurt. It's why I message people with new ads to delete any face pics.
Milo's face is blurred now but it's too late. The links to his Twitter profile and OF page don't help either.
