I often get reports with just “Breaks Community Rules” and no additional context. This is because Voyager automatically sets the mandatory report reason as “Breaks Community Rules” without actually adding a reason. However, it’s often not clear why a post would break those rules and which rule would be broken.
Fair enough, I do investigate more for the communities I’m actively moderating, but a lot of the reports are intended for the community moderators, and it’s not really my place to follow up on it.
Another common one is “spam”. We get a lot of legitimate reports for spam which I take action on. Sometimes a regular comment is reported for “spam”, and if it doesn’t look like spam to me then I will end up dismissing it.
