I remember, but I do not know what came about from it. I didn’t initiate the posts and I chose not to pursue contacting the sites where my work was posted. I had three poems from what I could see posted elsewhere, but I also have copies of my work time-stamped in various files as well. I learned a long time ago that writing and sharing publicly is a quick way to provide thirsty people with thoughts that they will not or cannot produce.
And from what I can recall, Medium didn’t really seem to be equipped to do much, either.
