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 Hive account@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.
