What you presents is sometimes just scratching the surface. Instead, you could reach out to the real artist and share those conversations with us. It will give a broader perspective on the artist point of view and ofcause tell the person that plagerism isn't okay here before posting your findings.
I do think you should post it either way and if the real artist doesn't answer you in a timely manner, you could still add the coversation, so we can see that you tried to contact them :D
Hi cwow2! Nice to see you around.
In tens of cases exactly what you are referring to was done in reports, for example, this is one prominent example:
https://peakd.com/fraud/@jaguar.force/id-theft-case-4-caso-de-robo-de-identidad-4-marloart
In every one of these many cases in which artists were contacted, a very thankful and favorable response was obtained, 100%.
That is some good shit :D Keep doing that :D
The last few have just been missing that! Steevc went to insta and ask the artist himself :D
Yeah I saw that. It was very kind of him. :)
