The reward plunderers are an annoyance. It's unfortunate that they top the trending page as they set false expectations and can give a bad impression to new users. We want the best content to be up there, but it's not always happening. We also have people buying massive votes to trend. I know it's people just exploiting an open platform in unexpected ways, but I feel it could be better. Some choose to flag to counter these activities, but you risk retaliation. We're still exploring what this platform can be.
