Do admins or moderators monitor these reports?
Sometimes, but not always. A Mod can't instantly see if another Mod handled it already, which makes it hard to keep track of this thread.
When I find plagiarism, I now click "Report to moderator" too. Something like "Plagiarism, please permban. See
https://bitcointalk.org/index.php?topic=2855895.msg33874667#msg33874667 for proof." is enough. I don't think all Mods can ban them, so the risk is a Mod just removes the post without ban.
For a moment I thought figmentofmyass was guilty here (luckily he's not!). I'm not used to this AM/PM-time, who came up with the idea that 12:51:48 AM comes before 03:37:07 AM?
