I believe the idea is you decide if you want them punished or not, this is independent of what the reports are for or who made them?
Sometimes people are too lazy to change the drop box to the appropriate offence, so I tend not to look at that. And when you review cases, it no longer indicates what the reports were for, so I think the what is largely irrelevant. The fact is, there are reports and your job is to decide if the behaviour in the games you've seen warrant punishment :)
