Um, Jules? Alexainie? Jennifer Brown? Anna Present? Solitary Cook? Check out what he’s posted so far. Look familiar?

Over-the-top compliments? Snide comments that are oh-so-gracious? No non-comment posts? No highlights?
Also, why would this CEO guy (you may need to click through, Medium picked a different photo on the page from memememobile.com; the photo on the site is the same guy as the profile photo, but the profile photo is also on LinkedIn):
…be posting stuff that the Medium “Peter Marshall” is?
It’s also possible that “Peter Marshall” is an AI someone turned loose on Medium to see what would happen. Some of the posts sound like they’re on the autistic spectrum, which fits AI personalities these days.
Either way, not worth y’all’s valuable time, IMHO. (Although I still like your poem, Jennifer! So something good came of it.)
But if you want to take on the troll (or AI, which would be kinda fun, I admit) get H. Nemesis Nyx involved—she LIVES for this stuff!
