Actually, the rights do not have to be specified. If I create content, the copyright is mine and you using it with or without attribution is theft.
You have zero proof of how @steemcleaners accessed the image. As I stated, for all you know, one of the volunteers could have had an account.
So, einstein, you stole someone's property and used it without their permission. You are accusing others of your crime with zero proof.
Actually, you are wrong.
The content in question that was posted by me was from public domain and unattributed because no attribution was found publically.
By going behind a paywall illegally, they THEMSELVES broke copyright law by accessing copyright material behind a paywall and without paying for it. Thus, they broke copyright law to try and prove that the content was copyright.
This is the equivalent of illegally spying on someone to prove they broke the law. They are not an authority of any type and no one from the platform gave them permission to do this.
They elected themselves as "policers" then accessed a platform illegally to use stolen data to prove their case. Smh, not too bright!
