In the end there is always this paradox between the ability to self vote and the ability to create multiple accounts, it seems that if you try curb one, the other will be abused.

I’m already working with the absolute minimum effort voting behaviour for returns, so not even denying anyone of selfvoting, creating botnets. Even identity based voting can be exploited. Fully embracing stakeweighted voting here on an open network environment and just wanna encourage more users to give votes away. And only way to do it is to increase curation rewards, which could also in turn make actual curation services more profitable and hence, desirable.
