How could a sane supposedly normal person come up with an idea of such a link? It's all part of the magical thinking. If you know someone's True Name, you have the power to require them to be polite. But if it turns out that you don't have their real True Name, your spells will fizzle! Geez, the more you think about the "civility" rationale the harder your head hurts.

Now the rationale of the "report your neighbor" link becomes clear: People who don't use their True Names are committing the mortal sin of... (shudder)... denormalization. Off with their heads!
