Because they are attention seekers. They look for attention, and pity, and admiration from others. Since they probably can't do that in real life, they come on here and pretend.
They want people to feel bad for them. It's most likely that when you're feeling sorry for them, and trying to make them feel better when they are "Down", they are behind their computer screens feeling successful and laughing at you.
That depends really. 1. They could be bored of who they are and wish for exciemtent 2. They are jealous of who they want to be and therefore pretend to be detto person to experience their lifestyle 3. trolling, just for attention 4. Could be the actual person, making a fake account pretending to be themselves (if that makes sense) to 'test the waters' so to speak before officially joining a club/site.
After all, if i were famous i wouldn't fan girls/boys screaming in my face all the time XD
Oh no, I'm sure they're telling the truth. Hardly anyone lies about who they are. Oh da the way, did I tell te that I'm actually Tohru Honda? Yup, my boyfriend even turns into a cat anytime I touch him.
I know it seems wierd for people to make up un-awesome lives as opposed to amazing ones, however somewhere in a wierdo human minds that if we say stuff like "My mom was killed right infront of me" o something along those lines, then people will give us sympathy. While in reality, they arent giving us anything, theyre feeding our alter-egos, and making us think that "Oh, this is a good thing, maybe if I make my alter-ego's life evn più suck-ish, than i'll get più attention." I guess humans are just stupid that way. I mean, we say were smart, but we trick ourselves so easily.
In all honesty, I've been tempted to do that a few times. Not for any of the reasons other people detto (i.e. attention), but just to see if I could. Test myself, because I think even if I tried, my real personality would still come out.
Were I to do that, however, I'd probably just unisciti a bunch of fanclubs about things I don't like, and answer things the opposite way from what I normally do. I wouldn't make up a sob story. So...
In short, everyone else is probably right. 85% of the time, that is.
