Well people don't voluntarily improve, if they can choose more rewards most of the time they will, look at steem, blurt, whaleshares, etc. Downvotes aren't extreme, extreme would be something the steem witnesses did when they stole the stake of hundreds of users. Downvotes help adjust things for the better unless used badly.
I mentioned Chinese as an example, if you can write in both languages that's probably even better for your reach, we curate such posts regularly.
