It would appear that way, yes. You are correct. Just as it would appear that as we find these folks doing it, we simply ban them and report their info to stopforumspam.com and let them sort things out with any other forums they'd like to join. However, if there is an issue with someone randomly sniping people with negative feedback, then you can rest assured the feedback would be removed.
It's only when people are plain lazy and/or ignorant and cannot be bothered to read and follow instructions that there is no hurry or pressing need for action in matters such as this one. As for the rest, we rely on the honor system in this regard. Spark has mentioned he can just simply remove iTrader scores entirely and be done with the whole damn thing. But since members find it useful and most use it with respect to the way it was initialy intended it is still here.
Unlike the issue with why bumping threads to the top and casual commentary was removed. It was also based on the honor system, but a handful of asshats would think it was worth the risk bumping their shit back to the top 5 times a day while trying to disguise it as back patting one another. We aren't slowing down at all, we've just getting started.
