However, as far as I know if the user deletes the post before a moderator actually handles it, it'll move to the handled reports, and a moderator likely won't see it. This is something I'd have to verify, and actually be on the look out. Moderators can look at recent handled reports, which means they could potentially verify if this has happened. For example, I just searched the recent reports, and have verified that the user was definitely reported twice, and either it was deleted by the user or another moderator. We can't verify without an admin, whether it was deleted by the user or another staff user.

The user that you reported at least on the thread that it was reported, the thread seems to have been completely removed, so that was probably the punishment that the staff user handling it deemed appropriate.
