These duplicate slugs are sometimes guarded against, but can still happen in a few cases:
- when creating a project, and adding a secondary hashtag that will collide with the derived primary hashtag.
- when editing a project, and adding a secondary hashtag twice (but not if the project already had that hashtag before editing).
