"Brainwashing is illegal."
Translation:שטיפת מוח היא לא חוקית.
שטיפת מוח, בלתי חוקית was not accepted
I reported it, but I'm curious if אינה חוקית would be accepted.
It works, people would understand it, but it's the equivalent of an English speaker saying "unlegal". The common thing to say is ״לא חוקי״
