Surely we could place limits on how much you can upvote a single user?
This would likely not prevent the kind of abuse that is happening.
So for example, you can only upvote a single user once every 24 hours or maybe a max of 10% if your VP can be used against a single user every 24 hours.
People just use alt accounts instead.
Agreed alt accounts could be used but if you could only upvote any given user once per day you would need a fleet of at least ten alt accounts to make it work! I appreciate you could do this but I think it would be less likely to happen and if it did happen, less noticeable so would cause the kind of wars currently ongoing. Just a thought.
