Keeping a constant eye on someone's activities may not always be viewed as a positive or respectful behavior. Instead of saying "follow/watch someone's every move," a better alternative would be to use other synonyms such as "monitor," "observe," or "track." Monitor implies a watchful and protective stance, whereas observe means to take notice and make careful observations. Track, on the other hand, refers to keeping a close eye on someone's whereabouts and movements. These synonyms provide more appropriate ways to describe paying attention to someone without coming across as intrusive or creepy. It's always best to be mindful and respectful of someone's boundaries.
