I’m glad to see the developers did something about it this hype train was so real for the last two weeks steemian shilling byteball and when the abuse started it was almost laughable at a point! It may have been some effort but those people made some decent coin to power up their accounts with!
All i know about it is what Dark has told me, but it seems like now people won't be able to power up random bot accounts to just upvote their own posts. Also making it more accessible for people to get their referrals they are intended to receive. Glad they made it hard for people to get around the system.
