Not possible to hide requester's e-mail when making Service Desk issues public
When an issue is created on the Service Desk, its title is automatically populated as such:
E-mail subject (from firstname.lastname@example.org)
While Service Desk issues are private by default, there is the use case for making them public at some point. When making such an issue public, a sensible thing to do is to change the issue title in order not to disclose the requester's e-mail.
However, the actual title change appears in the issue activity in plain text as a diff, thus revealing the requester's e-mail address without the ability to ever hide it. The only option to avoid it is to make the issue confidential again.
It would be great if there would be a way of not displaying the requester's e-mail address at all when a Service Desk issue is made public.
Here is an example of an actual Servicedesk issue https://gitlab.com/gitlab-com/marketing/community-relations/evangelist-program/general/issues/183
