I would argue we need to normalize downvoting.

But I understand. I downvoted steemitblog on Steem and someone came and downvoted all my steem stuff then came over to Hive and downvoted stuff lol.

I made a post about it to spread the news about that person and I ended up getting more in rewards than they wiped out.

It all comes around, but (for what it's worth) I feel normalizing it would be a good thing.
