When I worked in child protection there was a lady who was in prison for various violent crimes. She collected personality disorders like Yu-Gi-Oh cards. Her kid (little boy of about 6 iirc) was placed with a relative, but she was still the legal parent. As is typical with sociopathic narcissists, she blamed everyone but herself for her situation, especially the social workers who had dared suggest that starving and beating her kid while smoking crack wasn't the best parenting in the world.
Now there's not a lot you can do from prison to get back at social workers, but as she was still technically the legal parent she figured out there was one thing she had a legal right to do: change his name. So every few months (I forget how often you can legally do it) she would fill in the forms and change the kid's name. Again.
And when it came to names let's just say she went for quantity over quality. Every time she did this the kid would be lumbered with anything up to sixty new and ridiculous names. Obviously I can't remember them all, but her preference was for the names of trashy celebrities. I remember at one point the kid was called something like Lionel Messi Christiano Ronaldo Justin Bieber Kanye West Peter Stringfellow Barack Obama Jimmy Savile Hannibal Lechter Sherlock Holmes Alan Shearer Peter Andre Jeremy Kyle etc. etc. until he had another 40 names. Then as soon as legally permitted it would all be swapped round again.
And if the Police, prison, probation people, social workers or anyone else didn't use ALL those names, spelt correctly, in the correct order, at all times, her solicitor would threaten legal action. So the social workers, being social workers, dutifully did so, even if it caused buffer overflow errors on their computer systems.
Given her rap sheet (and her habit of shanking other inmates) I doubt she'll be getting out of prison any time soon and the kid won't be 18 yet as of now, so as far as I know this is still going on.
