One of the services now allows people to spend large amounts to promote their posts. I believe the daily limit that can be sent to one of the most popular is 9999 SBD.
They did this just for one week, another bot service that is shutting down is down voting every post that is using MB, so that's the reason!
Today in discord in the minnow booster channel one of the main bods was saying that was the current limit. It's the whitelist thing you see. It was limited to people on the whitelist but now because of the "war" that's the limit for all.
May be, I was telling you what I read and chatted with someone in their #minnowbooster help channel. I guess it would be good for Steemit if all the bots stop working with whales upvoting other people's content instead of selling them to these bots.
Who knows what the solution is but buying giant 100 dollars boosts ain't it in my opinion!
Yup, doesn't sound cool to me as well.
