Mind you, this is not a matter of mass reporting to get this done. Of course if mass reporting, only the media company will decide if to truly ban or not.
But in this case, we take charge.
I don't know how good your service is, because you have not posted a platform or a way to ban it, but I have doubt if you really can do that, there should be a violation involved with the account before it can be banned because if you are an outsider from one social media, mass reporting is the only way and it has to be proven, do you have a testimonial or a proof that you can really do that.
Do you think outsider cannot open the door without the need of an insider?
This is a service offering. If you did not see it done, get back your money
