We do not ready every thread and every post. However, we are expected to participate in the forums that we moderate, so we do read a lot of them. To that end, we are generally assigned to forums that we like to participate in.
We do not solely moderate based on post reports. Since we do read and participate in threads in the forums that we moderate, we will often see something and will moderate it before a post report comes in. We do very much appreciate post reports though, and often something gets reported that we did not see.
The moderation staff here is 100 percent volunteers. We are not paid. We do not have fixed schedules. We try to have enough moderators per forum so that we can quickly respond to most things, but sometimes our schedules line up in such a way that things get missed and sometimes we end up with poor coverage on a temporary basis due to someone being on vacation or otherwise being unavailable. We will often temporarily cover other forums in such cases.
We generally do not have the time to respond personally to every post report. As I said though, we very much appreciate those post reports, so if you see something that you think needs our attention, please report it. Even if you aren’t sure, just go ahead and report it. We get a lot of reports that start out with something like “I’m not sure if this is allowed or not…” We would much rather have too many post reports to sort through than too few.
