Punish fame seekers with jail spell

My most recent read was when a woman in England made false claims that a teacher had abused and sexually assaulted her daughter. This was probably the most serious one I read. However, this nut job only got 80 hours community service.
Now, I’m not expecting she gets a life sentence handed down to her, but seriously, she was near 40 when she did it. Surely a bit of common sense would have done here.
