The "Are you available" scam is still alive and kicking. If you receive such a message, even though the display name is a well-known campus name, check the actual email address of the sender. It's likely to be a gmail.com account incorporating the impersonated UNI person into the username portion of the address. Don't be fooled! Mark the message as spam and move on to the next message in your inbox.
If you do interact with the imposter, you'll be asked to buy a large quantity of untraceable gift cards with a promise of reimbursement. That won't happen and you'll be out the money you spent and also filing a police report for the fraud you experienced.
