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?
I don’t even know how you came to this conclusion. If you’re not interested in the discussion, and you’re not going to participate in it, why should you get to influence how others may see the content by voting on it and affecting its visibility? That’s the premise.
