I just found that a Indonesian Wikipedia page, that has been protected by admins to recreate, can be recreated by a normal user. The page should not able to be recreated, except admins.
Please see the protection log: https://id.wikipedia.org/w/index.php?title=Istimewa:Catatan&action=view&page=Cipto_Junaedy&type=protect. It shows that an admin has protected this page from creation since 6 October until 6 January 2017.
However, a new user created this page on 17 October 2016. See https://id.wikipedia.org/w/index.php?title=Cipto_Junaedy&action=history
Is this considered as a bug in Indonesian Wikipedia wiki?
