If I were to build a bot to report posts, 4 seconds would be well below how quickly a bot could identify spam posts.
Wow, that would be a breakthrough to put spammer out of works faster. But will it be very effective in assessing every reported post ? (if you did create the bot).
I firmly believe that you need a break from your current manual reporting activity. It looks like 4 second will give you a little chance to sigh. But you have such a strong interest in doing it that 4 second will be something long to wait. :v
