how can i tell if a facebook profile is fake?

[live long and lava on]

i think my friend make a fake facebook account for these two people she says are her cousins. There is A LOT of stuff that proves that they are fake but i don't know just how to prove it. I'm guessing she took pictures off of another profile. I don't just want to accuse her and then her get mad. thanks for any help.
Yeah they can never meet up and she has a story for everything.

Link me to the profile and I'll get to the bottom of it.

Start flirting with them and try to meet up with them, if they can never meet then, obviously. Or tell them something like your friend is annoying that only you would know and if your friend gets angry for no reason, obviously she knows.

Don't get mad, get even. Make your own fake accounts.

Its kinda hard to tell. I have seen like 6 different profiles with the same pictures before. Look at the way they post stuff, look at the faces of the pictures, if people comment on "her" pictures and she doesnt comment back then it is. And sometimes you'll see the same pictures with different names on the internet somewhere and then its obviously fake.

Looking the whole account like friendlist,likes,pics,info you can find out who are fake account..
