By the way why isn't there a negative vote possibility in the DHF like in the posts?

This feature is asked before as well. Currently return proposal acts as negative vote but it's not as strong as a direct downvote.

why isn't DHF proposals selected based on voter count instead of voter HP?

U can create one new account per week for 5k hp for free. It's not a solution. Account reputation system is also broken.

We wanted democracy here but we got the same bullshit as in real life, just with different people.

Can't comment on this statement.
