Lightweight topics will not earn downvotes while heavy controversial might drown in them. That is how the internet works everywhere. It won't be different here, which is a shame because Social =!= Fair, but we know that already...
The REAL meaning of a Downvote?
An upvote is not a sign of quality nor is a downvote the counterpart. It's just a downvote, a tool for ppl to cause tiny harm to the achievements of others.
I think the way D.Tube handels downvotes is way more natural behavior for a mass media society. Avalon lowers the visibility of downvoted content but doesn't cut the reward. In some cases, initial downvotes increase the curation rewards for later upvoters.
