If you see many bad posts or off-topic posts (due to spam or bumping services), you should use the template to report them:
"Off-topic post. There are many in the same topic, please check".
It will make your life easier because you don't have to spend time to report all of those shitposts you find in a single topic. On the other hand, there is another reason to think of: Your report points will do not increase if you do that. So at the end, it is your own decision that mainly based on your main purpose when reporting, and your spare time budget.
There is a script that can help you to more efficiently report many posts with same report template:
[HACK] One-click mod report, not for the faint of heart. Using this, your reporting speed will do increase but you have to obey timegap between reports.
