I would like to add that if a user has 25 or more reports, the good/bad/unhandled reports indicator is activated.
Imho, that is a good move and something I never understood, having a cap for report history being so high.
Speaking of it, why not make it immediately available after first good report? The only reason I can think of is that they want it to be a sort of incentive for people to report but I don't think its a very good argument for it.
