Fix for End of Payout Period Downvote Abuse
In Hardfork 17, a change was implemented to prevent upvote abuse by creating a twelve-hour “lock out” period at the end of a post’s payout period. During this time, users are no longer allowed to upvote the post, but they can downvote.

This change opened an avenue for abuse, where a user could downvote a post during this period with no opportunity for stakeholders to negate the downvote by adding additional upvotes.

Hardfork 20 will change this “lock out” period to a “cool down.” During the last 12 hours of a post or comment payout period, upvotes and downvotes will still be allowed, but their strength (for the same amount of voting power) will decrease linearly from 100% to 0% over that 12-hour period. In other words, it will take twice as much voting power to have the same impact on a post’s payout if the vote is done with only six hours left on the payout window instead of twelve. A downvote cast in the last minute would have virtually no impact.

This change has not been implemented yet, but we have decided to include it in the hardfork, and are tracking the progress here.

With this change all you do is to fuck both human content uploaders and human spam adversaries and change the effective downvotability period from 7 days to 6 days and 12 hours, whereas you left the effective rewardability period on 6 days and 12 hours, whereas in platforms like Dailymotion and Youtube it is unlimited the way it should be.
This favors automated behavior even more and supports abuse.
Humans tend to miss content the shorter the period of effective votability gets.
The votability period here was 30 days initially, which was still too short.
You made this an instant messaging platform stored on a blockchain.
I wonder if the origin of this proposition is a mildly corrupt moron with no better way to spend her/his time, or a fully corrupt preminer or one of their cronies.
I also expect her/him to remain hidden behind a github identity due to the shame and guilt.
