I'd concur: the university is the wrong unit-of-ban.

For example: what happens when the students graduate- does the ban follow them to any potential employers? Or if the professor leaves for another university to continue this research?

Does the ban stay with UMN, even after everyone involved left? Or does it follow the researcher(s) to a new university, even if the new employer had no responsibility for them?

On the other hand: What obligation do the Linux kernal maintainers have to allow UMN staff and students to contribute to their project?

It stays with the university until the university provides a good reason to believe they should not be particularly untrusted.

If they use a different email but someone knows they work at the university?

It's a chain that gets really unpleasant.
