@tripleee while SE is a community ran initiative are these times determined by your opinion or do you have a matrix to indicate that we have a slow turnaround? While we do have a broader scope than most sites just simply blowing away spam by a subjective spam detection that, if I recall, is run as a side project and not actually ran by SE tends to be biased, no? Also, we must take great consideration verses what is spam and what isn't since our scope is so broad. So what exactly is your goal?
The only times I am aware that may tend to be slower is on the weekends as we do tend to try and have a life beyond the site but if a question is flagged as spam we typically take care of it. So I'm somewhat confused in your objective. Are you just trying to increase our turnaround times or are you questioning if people know about your spam project?
