This is the second public set of post report statistics, for the period of Jan 1 to Jun 30 2011. These statistics are calculated based on the reports submitted when alerting the moderators to posts with the report post icon (). They are selected from a wider set of statistics I've produced for the moderators for the last five years; for privacy reasons, we don't release certain statistics such as those that identify individual members. Statistics for the previous period are here, including Doctor Q's comments on why we keep these stats and how you can help maintain the quality of forum posts.

The graph below shows some of the common issues and how the breakdown has changed over time. Notably, spam is by far the biggest problem. Duplicate and consecutive posts, as a percentage of all reports, have become less of an issue over time, while reports for personal attacks have been increasing. Reported threads Some threads, particularly long or controversial ones, have a large number of posts reported. 69% of threads containing a reported post received just one report, while 71 threads received more than 10 reports. The highest number of reports for a thread was 76, for Steve Jobs Taking New Medical Leave of Absence. The all time record remains at 110.
