Like bring the downvote option back but change the name of it to "Objection."Your still getting your point across that you don't agree with what that person said. Plus it sounds less negative and fun as well.
That wouldn't help. They would need to reveal all the people that have down voted you to make a difference. I think that is the biggest problem people had with it. Someone might down vote the statement "rape is wrong" and stay anonymous as they troll with their down votes. Or they would bully someone for fun. If they see that 10 people have already down voted someone, they would be more likely to down vote them just for the sake of joining in the bullying.
They shoulda never gotten rid of them in the first place. What would be good is if they put something in the bar on the right about it with a poll, but of course they know without asking what we want and we're just lucky to be allowed to use their website! ahahahahahahahhahahahahahahahahhaaha!
