Something else to note here is the quality and availability of data when someone actually submits a report. There's been more than one occasion where I click to submit a report, and the form pulls up fine, and I fill out the information and click submit, and then go about hopping out to take photos or look at other data. Five or ten minutes later, I realize the report didn't go through and refresh and submit, but forget to go back and edit to denote what would now be classified as a slightly delayed report. It's not a SN flaw, but rather a need for the user to pay for attention to detail I suppose.
This tends to happen in poor coverage areas, or when there are massive chaser convergences and slow data quality, but it can make someone look suspicious if you don't know the circumstances.
