Based on the monthly updated report handling statistics, I think the mod needs a little more time to handle the increasing number of reports. In the last 3 months on average there have been 39,402 reports the mod has handled with (not counting the March-April period) so I really think there is a lag in handling them.
But for certain cases I think there are also reports that are handled quickly including reports of plagiarism.
