As one of our labs, we decided to make a fake profile on facebook and send out over 100 friend requests. We were seeing how many people really trust their peers now-a-days. Usually, people would say that they would never accept anybody they don't know to be their "friend" on facebook, but when "Natasha Walker" made an account and set her school to "UNCSA" the majority of the requests were responded to. There were even a few friend requests sent to us!! :O
However, this could show that people are just trying to increase their social capital by accepting people on facebook, that are classed more as aquaintences, compared to close friends.
Out of the 137 requests that were sent, 90 of the requests were accepted!
