Justice has nothing to do with it. Bid bots divide the total vote in a way that's proportional to the bid (i.e. if your bid represents 10% of the total bids, you will receive a 10% vote). There's no guarantee that the vote will be worth more than what you pay.
For example, lets say bid bot X have a total vote power worth $8.00. If 10 people each pay 1 SBD for a vote, then the vote will be divided evenly between all 10 of them, amounting to 0.8 SBD (everyone gets less than what they paid).
It's not a scam and it's not a bug. It's the way it works. If the bot received more bids in the voting period than what its total vote is worth, then the return-on-investment will be negative.
Use a service like Steem Bot Tracker before making a bid to ensure that you're going to get a decent ROI. A brand new bot like this that was just announced is obviously going to see a lot of traffic. Once things settle down, I'm sure you'll be able to get some profitable votes out of it.
UPDATE: It appears that this bot isn't on the bot tracker yet. But I'm sure it will be soon.
hey man first of all you have to read this article their is mention that you will recieve upvote in 4 minutes this is not like a booster bot who when 100% power up divide the percentage and speedvoter does not give upvote when it is 100% u can check at steemd
I have read everything and accurately explained how it works. I'm not sure what you're still getting at.
see
Is this % divide he sent 3 sbd and get 0.26$ upvote before soo big reply plz gather info about it
I'm not sure I can decipher everything you're saying, but I'll try to respond. It is EXACTLY like booster in that you compete (or bid) for the upvote and then the upvote is divided accordingly.
But in order to maintain this speed, of course it won't be using a 100% upvote every 4 minutes. It would completely drain itself within a couple of hours if that were the case. If I did my math right, in order to be sustainable, it must vote with an average of only about 3% every 4 minutes.
No matter what percentage it's voting with, my original answer still stands:
"Justice" has nothing to do with it. This is simply how the system works. There's always risk in using bid bots. There's no guaranteed return on investment.
