I haven't made the proposal yet. It should come soon and I'll make a shorter post when that is ready.

I've also been downvoting before. I used to give around 10~20% of my votes to downvoting. The problem is I don't get curation rewards for that. They get curation and usually author rewards too for buying votes as you fully know.

This is just playing the system for profit whilst adding no value.

Agreed.
