Roastbook is an (anti) social network. It does basically what the name implies. You have to roast each other. The Key to 'succeeding' in this network is to write the most creative roasts not the most insulting (though that might give you some points)
In our CS class at school, we got the assignment to write 'something with databases' and because I had a bit of experience with databases and programming. We set us the goal to write a (more or less) Social-Network. And because we wanted something a bit more unique than all normal networks, we decieded to build a network to roast others.
