Well, what people sign up for and what people actually do are two completely different things, no? If I come to work, then I obviously came with the intention of working. Actually doing my job is something else. You see where I'm going with this?
I just hosted an audio competition where less than half of the contestants showed. So, yes, this site is called Rap Battles but less than 10% of the people actually rap or battle... or contribute anything musically, really.
Stop making it a big deal, lol.
