I ain't the bloke that set up an account pretending to be someone's mother and then set up another pretending to be a young girl.
Well we have a bloke on here that pretends to be a woman, a London boy that pretends to be Irish, a nasty collective of armchair fans called the 85%ers, a play loving Edinburgh based politican / enviromental consultant, a jobless lunatic that gives us ****e tips on horses, a McDonald's worker that loves talking about his rival football team and the dullest guy in the U.K called Toby. So yes, it is quite believable that someone has created a fictious account pretending to be a young girl.

Don't forget the bigot who hates himself so much that he pretends not to be Irish and is violently abusive to anything related to Ireland/Catholicism.
Every day that you survive, the Earth gets darker and one extra glob of grease is added on humanity's current step in the food chain.
Not forgetting the most boring angry **** in the universe, Toby. And that includes the boring aliens as well.
