Nobody checks Promoted because it’s a poorly implemented feature. It needs to be fixed by STINC - or other interfaces need to step up and make it a viable feature.
But I still don’t see how this method will work out better for the people using Promoted. I think this is more likely to receive backlash, as other users will see the duplicate or link post as a low-value post that’s over-rewarded.
Put pressure on STINC and other interface owners to create a better promotion feature for users. I think that would yield far better results in the long-run. It’s definitely something that could/would be extremely beneficial.
