Edit: I propose, like we call sovereign citizens SovCits, we call these people AmArchs for amateur archaeologists.
Please don’t. SovCit is a crazy ideology, whereas there are actually very knowledgeable amateur archaeologists, heck you can even get archeology courses from professionals here. I’d prefer them not getting thrown on the same heap as the nutjobs that posted your wall of text. Although I don’t have a viable alternative at the moment I’m afraid.
