There was a women on a parenting forum I use that lied and deceived everyone on it for years. She pretended she had fertility problems and made up ivf treatments. She then said she was pregnant with twins but lost them, more lies, then lost more babies and had everyone feeling sorry for her but the whole lot was made up. Someone else also did a similar thing saying she lost a baby but then was pregnant with twins and was found out. Scarily these were both users that had been posting for ages and people thought they knew. They even stole photos from the internet of people and their children and pretended they were their own. Certainly makes you think.
