Well, I tried to talk about this with steemcleaners , but they've ignored me on Steemit and Discord too. Later another User with similiar Postings like mine and more SP started to contact them on Discord and he has got an answer.

In fact, one of these Cleaners don't like Postings which have to do with Christianity, so he downvote them and think it's good to do this. At the beginning I've made Screenshots about this conversation where he told this and insulted the other one for a long time. I wanted to present the community what's going on here, but then I decided not to post this because it would be senseless to provoke people who have nearly limitless SP.

Meanwhile I try to accept/ignore what's not righteous and I'm glad just to get low downvotes when I to show up all sources and proof on this way in Postings that no Copyrights has been violated.
