I can safely assume that more than 50% of the authors and newly backed users will do that.
Right now they can also do it by using (or misusing) the flag. But they don't (at least most of them). Good authors have their reputation at stake which prevents them from misbehaving.
Totally true but i wasn't saying about good authors with reputation but about the ones who want to succeed in any way, including downvoting everything, and i have seen many.
But those guys won't be able to make any significant impact on the payout - most of them don't have much Steem Power.
1 .. 10 .. 20 .. probably not. Think high numbers of alt accounts created especially for this: 100+ that would make an impact.
Fortunately, it's not the number of accounts that matters but the amount of Steem Power they have.
@ i have got a downvote and my reputation is down at 12 i need some serious upvotes to increase my reputation please kindly upvote me so it help me
