Vilain garcon and garcon vilain - Quiz marks "garcon vilain" wrong

Question

Even Aurelie gives "garcon vilain" as an example where the adjective can go after the noun.  (ugly boy versus mean boy).yet the quiz won't accept it.  This should be changed

Accepted Answer

Bonjour Sofia !
Yes indeed, you are correct and thank you for pointing this to our team :)"vilain" is one of these adjectives that can be used either before or after the noun, and will change meaning accordingly.
un vilain garçon -> mean, naughtyun garçon vilain -> ugly (old-fashioned)
The reason it's included here is that the second use is very antiquated, and therefore you will more likely encounter the first case in common French.
However, the second form is no way incorrect, and therefore shouldn't have featured in this question. Thanks to your feedback, I've now removed and replaced the question with a better one.
I hope that's helpful!Merci et bonne journée à vous !
