Hello everyone!In my part,I will discussthe privacy issues in social network with these three aspects:users,socialnetwork,and the third party APPs.Social media are Internet sites where peopleinteract freely,we share our photos,our likes and dislikes,our thoughts andstatuses more freely than any time in history.But still,it's not like we'resharing everything about ourselves with the rest of the world.Should we trustcompanies like Facebook to honor our privacy and keep what we share secure seriously?I don’t think so.
Socialnetwork already have access to personal information about you.The informationincludes your name,your friends’ names,profile,gender,user IDs,connections,contents and others.The default privacy setting is set to everyone.Yourprivacy settings only control who can see the stuff on your social network.Ifyou are uncomfortable with your stuff being publicly available,you shouldrevise privacy settings.But how many people aware of these problems?

I've just given some suggestions to mostly wording rather than the overall structure,with the parts in question putting in [ ] and the suggested one's in ( ).The thing I'd like to remind you of is the confusion you brought to us in the uses of "you" and "we","your" and "our".
