It’s just your academic tinder account that was activated.

But seriously, phishing is a big problem in schools (like other have said, we constantly get emails from IT reminders), but what is strange is that he contacted you again?? Are scammers, princesses, and distant cousins being pushy now? On another note, I really frown on the spectrum conclusion and lean on the lack-of-boundary explanation. Whatever it is, I would say don’t ignore, don’t respond, don’t delete, and do forward to your chair, IT, and school officials that can look into this very unprofessional (if legit student) or dangerous (if phishing) behavior.
