Attention Whoring

I really don't get the idea of getting too much attention on social media. Some people will pose almost nude selfies, more skin, more pits, more everything that can get someone's attention and eventually spark up sexually induced conversation and gather more praises about how they look and how they came about their lives. It's like having a reality TV show on your own less the roving cameras and equipment. 

What do these people get from it? Assurance? Proofs that boosts their ego? I don't know. I just find it sick to the core. It is a disease.
