Hi! So glad you are doing something about this. I have been here only 8 days, and can't believe the infringement going on! It's almost worse than I have seen anywhere, as new users scramble to post the best stock image they can find as eye candy - even going as far as entering them in competitions!
What I would like to see is perhaps something in HUGE block capitals for new users to sign stating that they will not use stock images and other images from the web that they are not authorized to use for monetary gain. I would also like to see them sign something that says they understand that if they falsely represent work as their own, or steal stock images from the web, their account will be blocked! They need to know this in no uncertain terms up front.
Although this is supposed to be a blogging site, most of these infringers have never blogged a day in their life. They are just hoping this is some get-rich quick scheme where they can earn money at the expense of others.
As far as I know, I have not had anyone copy and paste my images yet. Why the heck does Steemit allow this? I had no idea!
