The government does not operate like that over there. They do not shut down a farm for this sort of thing. They will shut down construction sites and yes there have been funny stories where the archies scrape a site and deposit that in a land fill. The hobbyist finds out where that land fill is and make fantastic discoveries that humiliate the professionals.
By “over there” do you mean the UK in particular or Europe in general?
I have no current experience, but I do know that in the 80’s in France and Italy, they were shutting down farms whenever anything was found.
