No, just the opposite. If a person gives an excessive upvote, they are the ones that should be punished. maybe not to reputation, but perhaps for the next 30 days put on a vote limit. strict 10 times a day only and at 1/100 of what their vote would normally be valued at.
Now what would this do? It would curtail vote selling,vote buying, and mean that they would not be able to use for those 30 days a vote curation trail. Their account value remains unaffected, their ability to <b.earn is all that is affected.
Vote negation I can get onboard with as well if done correctly and with enough safeguards, but "punishing" would be a lot more offensive and risky than "restricting".
