To see your report history, you need to have at least 300 good reports, not 300 reports.
God, I did not notice this too. You are correct, 300+ good reports, not 300+ reports as I posted earlier that is not correct.
Report History Only users who have reported 300 good reports have access to this page This is probably one of the most useful features related to reporting. Basically, this shows you a history of your reports, and whether they have been marked good, bad or are unhandled. This page can be used for ongoing evaluation of your reporting habits.
