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?


As much as it pains me, I think the only solution to vote manipulation is to disable downvotes. Mind you, I don’t like it - I think downvotes are useful in a healthy self-governing community - but here’s my rationale as to why it’s the only solution:
PieFed, at the discretion of community mods, offers restriction of voting to only subscribed community members. This limits drive-by downvoting from All, where people would not have read the community rules (which in PieFed are repeated in their entirety at the bottom of every post from that community).
It also offers restriction of voting to only “trusted” instances, thereby introducing a third category between the binary federation vs. defederation.
I have also seen communities on PieFed that disable downvoting entirely, even to subscribed members, even on the same instance.
Community mods can enable or disable these settings at will iirc.
Gog disabled down votes on its forum and now there’s a bot up voting every reply in derailed threads. Mass up voting can also be a problem in creative hands.
Vote manipulation is done in both directions
I know? I didn’t say it didn’t happen, I said that positive vote manipulation can more easily be addressed with spam prevention measures.
I have to say, I’ve always admired the Stack exchange system. Yes, it’s a Karma-like system, and it’s obviously not perfect, but it means that accounts always start with very little abilities, most notably that they’re not able to downvote yet. And when those accounts do get the ability to downvote (which doesn’t come all too quickly), it costs a certain amount of their “reputation”, which makes them think twice about downvoting.
I suppose that would address only a part of the issue and there are other, less intrusive ways to mitigate the effects of malicious early down voting. For instance, early down votes could be weighed less.
Or disabled until a certain number of upvotes are reached. It could potentially be disabled again of upvotes falls down under the threshold again. Or just have them time gated.
