I apologize if it seemed unfriendly. I tried to explain why it's still plagiarism.

Try to see from other perspective... there are networks of accounts that regularly post stolen content, trying to use their own stake to extract value from rewards pool and lure unsuspecting Hivers to supporting their stolen content.

Always they pretend to be unaware, not to know that stealing is wrong, or that failure to source is stealing. Usually deeper research reveals their connection to known groups of abusive accounts.

So you can see why groups oriented around dealing with massive abuse on a large scale may sometimes get an actual new person and not be very sympathetic to "I did not know how to identify source correctly".
