When I searched myself, I just found other Justin Lee’s because my name is very common. https://www.google.ca/search?q=Justin+Lee+Coquitlam&sxsrf=ACYBGNT4pgbFs2vh3v7ox3nCFg4wnI1Tiw:1579742082532&source=lnms&tbm=isch&sa=X&ved=2ahUKEwid1qntxZjnAhWzHzQIHYIKD7cQ_AUoAXoECAsQAw&biw=1368&bih=799

Questions

To keep my digital footprint safe and appropriate, I would make my profile private, not share personal information with other people (even friends), and not talk with random people/strangers.

If I had to pass on information with other students, I could just use technology to reach out to them and pass on the information.
