Specific requirements:
Use Safari browser to edit frequently vandalized English Wikipedia page on iOS device
As a new user not logged in attempted to edit a page, a notification popped up with the notification "This page is protected to prevent vandalism". It also displays a locked pencil. However, it does not provide advise as to why it is locked or what to do next. This discouraged a new user that did not know they needed to create an account or attempt a page that is not as likely to be protected.
