No. It might effect your chances of ever becoming a mod if your accuracy isn't very good though (if that is something you would be interested in).
lol. So I can't be a mod any time soon?

You have reported 12 posts with 40% accuracy
Not anytime soon but you've got plenty of time to catch up

, though there's probably a handful of people who will likely be next in line with 1k+ posts reported and high accuracies of 90%+ so you might be waiting a while

. People should just keep reporting and don't be discouraged and your time may come eventually. Mods always come and go so new ones will always be needed.
