I believe that students should expect that their privacy will be protected given the volume of information they share on the Internet, exactly because they share so much information on the Internet. The right to privacy shall not be infringed. Be it in the media, or through the mail system. We have laws that address this topic however they haven't caught up to the technology.
The Internet is one big jumble of information that once it is posted, it is truly impossible to remove it completely off the Internet. Students should be extremely careful with what they post because one day it may come back to haunt them when they are applying for other schools or even jobs, because companies now can look your information up online and see anything that is associated with your name, hindering your ability to to get certain places in life.
