Well, I don't really mean to be derogatory [forgive me if that's how it looks to you]but, what sort of post do you report?
Nearly everything that should be reported for keep the Forum clean and other Users safe. 
Spam posts , Double posts , Wrong made board threads , Ref links , Scammer posts , Malware and Suspicious Links and so on.
If you want to dive deeper into that , take a look here Report Malware and Suspicious Links here so Mods can take Action !
You've got a little language impediment - that could be because you don't speak English as your native language?
Wtf why i should have a language impediment ?English is not my native language thats right , its german but I have been speaking English fluently for several years.
So for me there is no problem on the speak language front.
how then do you evaluate good post? Just asking 
Simple answer , with Merit and not reporting it.
