If spam reporting is rewarded in whatever way,it will only increase work load on staff as people will start reporting every other posts and staff will have lots of work to verify them
We're currently in a situation where too little reports are being made, hence "increasing the work load" wouldn't be a bad thing.
I don't see anything wrong with giving the mods work (reports) to do, it's their
job after all.
I don't think it would help the mods if there were incentives to report threads, it will cause many user to report legit threads. That will only annoy the mods for the perpetual waste of time.
Easy solution: Only reward valid reports. People "spamming" reports that are invalid would soon stop when they see it's having no effect at all.
People usually report threads because they are outraged by the particular mods, not because it will benefit them personally.
I don't even...Most people don't report at all, btw.
