See parent ticket for context. In our platform, "account deletion" takes the form of the Vanishing process. Per the new Apple policy we need users to be able initiate the vanishing process via the app.
The meta process is documented here:
https://meta.wikimedia.org/wiki/Right_to_vanish
There are two paths for these requests. Accessing and editing a Special page for Renaming. Or sending an email request to the renaming queue. For our purposes I think it would be both simpler and more user-friendly to create a simple email generation form that collects the required information and submits it to the queue.
The email solution also allows for easier closing the loop on when the process is complete, or the request is rejected, but providing a contact point for the user outside their (now deleted/logged out) Wikimedia account.
Intial proposed copy:
"To preserve attribution, it is not possible to delete an account on Wikimedia. You may use the form below to request a courtesy vanishing[link]. Vanishing does not guarantee anonymity or remove contributions to the projects.
If you want to leave Wikimedia projects but do not care in your past associations or intend to rejoin Wikipedia in the future, simply stop editing. You may optionally add {{Retired}} to your userpage.
If you want to edit using another username, you can log out and create a new account or use changing username[link] and clean start[link] instead.
If you want to hide personal information, consider oversight[link].
To initiate the vanishing process please provide the following:
Username:
User or user talk pages for deletion:
Additional inforrmation:
The Wikimedia projects will delete personal information about editors and contributors (most likely on user and user talk pages) at their request, provided it is not needed for administrative reasons (which are generally limited to dealing with site misuse issues).
Personal information related to encyclopedia articles and persons mentioned therein are not covered by "right to vanish". Instead, please see the relevant editorial policy on biographical articles[link], which contains full details of editorial directives, and actions to take if dissatisfied."
