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?
This! Lemmy/Piefed needs metamoderation.
The fact that scores were bounded to a predefined range ([-1, 5]) helped a lot, too.
I like the idea of a weighted rating or star system
