Posted by Scootalove Well in that case I guess it is abusing the rating system.
Though the "rating system" sometimes doesn't always work out: like I could post a pony spray and someone could comment "ur a faggot" or some crap like that. Then the rating would probably stay and you'd have to seek out a moderator for a resolution.
Moderators generally trash unhelpful comments, they unfortunately also remove all sense of accountability under the blanket statement "cleanup" in this way as well. However it is also the submitter's responsibility to make sure their submission is desired among the community. Take for example the wave of gold skins that flooded the feed a few months ago. The desire for those skins were minimal at best, even the submitters had no desire to use them. This lead to a mess of low scores. There are more factors that go into a well received submission than people ever consider, but they are quick to complain about it.
