Advice needed: Guys and Gals, do you think this is stalker behaviour?

I noticed a pattern of the same guy repeatedly viewing my page when I checked my profile visitors after logging into my SM account. I've never spoken to this guy before, so I'm a little freaked out. Is it better to message them or block them? I'm worried that if I block them, they'll just create another account. It began a few months ago, or so it seems. Help, please. How should I proceed?
