I'd say it's worse than that. This new policy of vetting will be extremely high cost in terms of time, money, and lost opportunities for students and universities, while also be rather useless in practice. Seriously, what student applicant won't clean up their social media profile? What threats will actually be caught by this approach?

This whole policy is dumber than conventional security theater.

But then again, that's the point of this policy. It has the thinnest veneer of being for a legitimate purpose while hurting those that this administration wants to hurt.
