Reports are like missiles launched at your intended target. Now if they are frivolous, they are not going to hit and they are going to count against you as a miss.
Things to report: Blasphemy, Profanity or implied profanity, Spam, Disrespect for Staff, Plagiarism, thread hijacking or trolling. If you are not sure, don't hit that report button.
Thinks not to report: Spats between members. Debates get heated. Also keep in mind the bias of the forum. Make sure you read the rules before filing a report.
You goal is to avoid getting your name on this Nugget list. The one with the most misses will be announced at the end of each month.
