The issue with downvotes is that those are tools for protecting the platform from spam and abuse but some people tend to use them as a mean to bully small accounts. And when big players enter this silly game nobody dares to raise their voice, let alone taking serious measures to prevent or protect the victims.
I know the system is still under development, but downvotes are abused as much as the economic system in the platform. We have some sort of anti-spam initiative backed with lots of steem (steem cleaners) but I am yet to see a supported initiative to protect users from bullies.
Time will tell tho, I think that we still have time to dare and prove stuff.
Best regards.
