Then you should know better. Please state the Statutes you think allows you to take other people copyrighted images and used them for a purpose of profit so I can show them to my Lawyer and the other photographers can do the same.
Laws aside you really think this is ethical... You do nothing but take peoples work and write some text which would doubtfully pass and an editorial (which still requires permission, but will allow exceptions for trademarks being in the images, etc) and they are making nothing and you $300 - $500 a post a day?
I'm working here and I don't have the time to teach you the obvious. But you should go to your Lawyer and let him explain it to you, he is paid for that.
People are being sued right now for taking other people's images and using them as content to monetize on their accounts. You're fronting and hiding behind a pseudo-name. You have no clue about the laws or what's going on right now.
The circuit courts will decided soon enough and establish legal precedence in this new internet age, but so far you can't do it.
Curation on the steemit platform is done with voting and you receive a payout from that. You can't steal other people content, you're a shit lawyer if you believe that and I know enough lawyers to know you're not one.
Thank you for your contribution to jurisprudence. Good luck to you.
