I'm working on a english question and need a sample draft to help me learn.

Many people are unaware that their social media posts may be scrutinized by more than just their intended audience. High school seniors have had their college admissions offers revoked based on their social media posts, and people have lost out on job opportunities when potential employers saw their postings.

Employers and colleges have a legal right to do this, but is it ethical? What are the reasons that employers or colleges might pry into someone's social media posts? What are the pros and cons of their doing so?
