Others' contribution to my dull life

I just don't understand why people could not be responsible for what they have done. And because of some people brainless and irresponsible act, university have to take action, of course the action taken are ridiculous as well. All I can say is undergraduates here in my current university have no life. We lead a dull life as social web pages such as Facebook and Twitter are blocked. Indirectly we're told not to make friends nor stay connected with people far away in the easy and economical way.
