Fakes

Why are there so many fakes on this website? I didn't notice until a friend told me all those not active accounts were probably fakes... eh I just stumbled across so many of them...

I don't think I could act as someone else, uwa haha. Maybe I'm really just a terrible liar and a shitty actor. At least I can dance?
This is a stupid question but how can I know who's a fake? I mean most people who talk to me on this website seems pretty real but I've seen some unactive accounts.
Eh I'm so technologically retarded I'm started to worry about using my mac again.
