There's one word to describe them Fake.
I see no need for these types of people, i pity them. They have an idea that they must put on a facade in order to entertain and attention gain. They talk in voices that aren’t them, they dress in manner to attract attention, and they publicly display themselves on social networks in a way to attract attention. They’re sad.
But the only people sadder are the people that fall into the trap of the attention seeker. The people that are led to believe the attention seeker and give them the attention they desire. These people will one day suffer the consequence in believing in someone who wasn't worth believing in.
