This appears to the post they blacklisted you for @mariya-lorenz. I'm on your side though, and I'll continue to support your original works.
They often won't respond to comments for some reason. I don't know why they think this is spam.
By their own made-up rules, you likely have to enter their discord channel and provide proof that this is your own original work.
It would be nice if they could let penalties for petty violations like this expire, but I do not think they ever remove people from their list after a set period of time. And their comments do not state this. That would be too fair!
The truth is somebody has been rewarded with a profit because they fraudulently reported this post as spam.
Beware if you decide to enter the @steemcleaners discord. They are not a great customer service system from what I have witnessed. If you have a personal blog where you also post your photos, that might be a great way to prove to them that your photograph is original.
