Those are like 15 SP accounts and there are many of them, all controlled by one account. All just no power serial down voters,. Poke around their profile, wallet, block chain explorer and you will see them for what they are. Also those down votes are so low powered with no rep to speak of they don't even impact the payout at all.
I've had 4 or 5 of them down vote me, just ignore it or go down vote the one post they may have made and help sent their rep to 0.

Yes @chromiumone , I see that there are many of them and they do not have much power, but it can affect other small accounts with good content and damage their reputation that needs to grow. It may be enough for small accounts to grow not staying here on Steemit. therefore, there should always be a comment with a warning before you can use the red flag.

Hi @teenagecrypto

Yes, it's a shame,
did they say why they gave you dovnwote?

No

Hi @teenagecrypto

Then it would be nice to have a yellow flag with a comet so you could understand why it was done

But they were bot accounts created by someone.

Yes @teenagecrypto , there are several such services that will offer autodownvote to users, it is scary
After all, there will only be another major flag war
