i have had this happen to me. It frustrates me, there are many reasons i am not on social media haha.
I have seen it happening here on medium, it is frustrating to me as a creator.. we can write about similar things, but we are each unique individuals and the stories will never be the same, unless the story is copied. I do not folllow a handful of creators who i have seen do this, and it just makes me sad. I just think, be original, and if you can't at least give that person the credit they deserve!!!
Great read, and your research is impressive!!!
