Alongside the jail sentence she had to pay the victim around £1500 compensation (!) and is not able to have any contact with her for 10 years.
Neither of which are enough.
I've noticed that people who want to work in jobs helping people, as the victim did, especially if they're passionate about the idea, can lower their expectations when it comes to the job. Easiest way to look at it is someone who has a corporate job leaving to work for the charity sector. They'll accept a pay cut and inefficient systems (which make their lives more difficult) because they want to be helping people. Were that salary and those inefficiencies in their previous job they'd have left a long time ago.
The victim had a dream of working in child protection. Someone lovely told her she could. She believed her. She didn't think her lovely friend would be scamming her. And it didn't start out dodgy either. We may not all have fallen for it entirely, but unless you don't trust your friends, you'd be unlikely not to have trusted her in the beginning.
