I actually went on a reporting spree a few weeks back.  In a few days I got up to 900 posts reported with a 98% accuracy!  Reporting one liner shit posts in Off Topic and Politics & Society, it was literally like shooting fish in a barrel.  Then the next time I logged in and reported posts I made it to over 1k reported and my accuracy % dropped to 88%.

It seems like the last 100ish I reported nothing happened.  I've since basically stopped reporting posts in the OT and P&S subs because if the posts are not going to be removed then I am wasting my time and the mods time by reporting it.  Perhaps it just isn't time efficient for the mods to trash posts in those subs?

When I see people say "report to mods more" I chuckle a little and think, ya I tried it, not too effective so meh, only in rare cases do I use it now.
