The thread you linked to is my solution. It works fine, I can queue up to 100 reports (possibly even more but I've never needed that, and reporting more than 100 posts at once would probably indicate that I'm overdoing it) and go do something else while it's working. TBH I would not want a shorter interval because the number of times I screwed up and had to cancel a report greatly exceeds the number of times the limit has been an inconvenience. 4 seconds between reports gives me plenty of time to react.

It's funny to see Quicksy harping about building a bot to report posts automatically after he attacked me for allegedly doing so even though I've never done that - always review my reports before submitting. Even if he were to build a bot he can report 20000+ posts per day with the 4 second interval... there aren't that many new posts per day.
