Hi Alinhimself, thanks for your comment. About the Whitelist part, as seen in the screenshot below, only those whitelisted can access to a bigger portion of the voting pool. This is due to vote sellers, setting their account to vote only to those users with a minimum threshold of posts quality. I.e. I put only to vote on Whitelisted users with "average content" or above. This is since I prefer to only vote to verifies "non-spammer" users, as myself many "higher" SP prefer to do the same.
Got it now! Thanks.
What's the average roi on that category right now?
I would say around a 10% though we need more vote sellers since as the demand grows, the number of votes available for purchase decreases. accordingly. Also, I recommend putting a limit to your voting power, like saying vote only above 80% so you still can use your own votes manually. I.e. for upvoting on comments in your own posts.
