- Users cannot follow a Prospect account.
- Users cannot like or save shots that have been uploaded by a Prospect.
- Prospects cannot leave feedback on shots or receive feedback on their shots.
- Prospect shots are not visible on the public shot feeds.
- Prospects cannot list themselves as available for hire.
- Prospect accounts are not publicly visible and require a user to be logged in to be seen.
