Actually I didn't even know there was suck a tickbox
If you're interested, here is what it's like for us to handle a report. We have a list of all open reports per forum. We can open each one to see what message was logged and see the post that was reported.
We then can close the report, edit the post, remove the post, pm the user in no particular order. The system is also unaware of the relation between actions done by mods and the report (afaik).
In any case, I'd like to encourage everyone to use this functions, it helps us a hand, to say the least
