Remember that you can use the report button for more than just reporting rules violations. If you see something that "might" be questionable, you can use the report button. If you need an ad deleted or almost anything else that a Staff member can do, you can use the report feature. Please also add a bit about why your are reporting. Sometimes we get reports that don't really have a basis, so if you can clarify briefly, especially when you are just asking, it helps us see the whole picture.
Sometimes we take no action and sometimes we discuss and sometimes action is taken immediately depending on the circumstances.. Like Sumi said, reports are confidential and reporting something doesn't mean someone will automatically receive a warning or infraction or anything like that.
Reporting is really more of an alert. It makes your report available to any Staff member who happens to be online. PMing one Staff member may have you waiting for an answer or resolution. If your issue seems to be urgent or time sensitive, please PLEASE use the Report function.
