> What's preventing those bad actors from not using a UMN email address?

Technically none, but by banning UMN submissions, the kernel team have sent an unambiguous message that their original behaviour is not cool. UMN's name has also been dragged through the mud, as it should be.

Prof Lu exercised poor judgement by getting people to submit malicious patches. To use further subterfuge knowing that you've been already been called out on it would be monumentally bad.

I don't know how far Greg has taken this issue up with the university, but I would expect that any reasonable university would give Lu a strong talking-to.
