(At least) on nl.wikipedia.org:

When trying to submit a new moodbarcomment (as new user) or when trying to answer a moodbarcomment (as normal user) you'll always trigger moodbar-abuse-title and therefor you'll be unable to post feedback or answer feedback.

When trying to answer "<moodbar-abuse-title>" is shown instead of the contents of MediaWiki:Moodbar-abuse-title and the corresponding body text. When trying to submit a new moodbarcomment (not reply) as a new user, the correct text is shown, but one is unable to post any moodbarcomment.

As Moodbar currently can't be used, I have marked it as critical.
