Put simply, if someone created a facebook account under an assumed identity and "just used it to repeatedly view someone else's public content," they could not be charged with stalking in Massachusetts because stalking requires that the person's conduct seriously alarms or annoys the other person and would cause a reasonable person to suffer emotional distress, and if they only used it to view public photographs, neither of those two things could be true. Stalking also includes a requirement for a threat directed at that person which is missing from your hypothetical.
