(Thanks azircon for your comment).

Referring to your post. I would like to know which artist was yesterday falsely accused as you avoided giving any details of it so we could all see and check up validity of your claim ourselves.

Also, just because there is pervading deception, dishonesty, content theft and plagiarism being spread around all social media making stealing or plagiarizing someone's art, photography or writing becoming a norm, it does not mean that it should be allowed on Hive.
No one pays you on other social media/blogging platforms for publishing content. Sot hey all steal and plagiarise.
Once there is any possibility of earning added to any of these social media/bogging sites out there, they introduce strict rules about use of someone else's content and have repercussions for not following these rules (banning, stopping earnings, removing the content, etc).
Hive is not Facebook or Reddit. We get paid a buck here to post honest and original work.

Also, just because image is from Pexels it does not give a right to someone to use deception directed at the community making their post look like they are author of that photography (by avoiding giving a source of photo) or making post look like they are complete author of the artwork making it look like they have completely drawn it from scratch (while they actually used the photo which they traced so most of work was already done for them).

So if I take your photo or drawing from your Facebook/website (even some that you forfeited your rights or sold to Pexels or Shutterstock), put it in App to use as under layer and then use this app to trace all the lines over and add new colors, then I will be all fine to publish it on Hive without any mention of the source. Making my "art" and post look like am the whole creator of this craft without use of any help?

I cannot draw or paint at all. I am completely useless when it comes to such artistic skills. I tried that app once though. You just put random photo there and used few tools that 8 years old can master. I traced the lines of the photo, added some colors and auto generated patters. And the final piece looked like really nice legit piece of digital art. It took about 15 mins to create. App did most of the work for me.
