Vote manipulation is getting more common. Some recent examples:
While the accounts were banned, the malicious voting activity stuck around.
Should admins have the ability to discard votes, and if so, which admins? Should community mods have that ability? Can you think of any ways that tools like this could be abused?
Piefed system doesn’t punish those who do not act “the way the creator wants”.
Downvotes given are only actions from the user, no interaction from the Piefed dev.
Downvotes received is feedback from other users, no interaction from the Piefed dev either.
Trolls are already around, as you pointed out in another comment. I would rather have a tool that works 80% of the time to detect trolls than no tools at all.
