I have heard that convincingly debunked as impossible with the larger more complicated designs.
The makers come up with the designs; some have meaning (some have been used as advertisements!)
I have never seen a pic of one used as an advertisement or of any known symbol from human history. I'll check the site you gave address to.
Since it's not a major crime, there is no reason to "rat out" anyone.
I didn't mean that in the sense that a crime was committed but I would in fact think that farmers don't appreciate it and it would be a crime to destroy their property. I used the term only as a manner of speaking since their origins have created so much interest. One would think the creators would take credit, give interviews, write articles and so on and on ...
Some farmers actually agree to let them do it. As far as the debunking goes, the makers have actually filmed themselves doing it, so you'll have to check those debunkers. You might be dealing with some Art Bell types there.
The makers HAVE given interviews, taken credit, and have written articles. Start at with Circlemakers, and go from there.
They do a LOT of commissioned work.

Ooh, *this* should be entertaining. Please present this "convincing debunking" which shows that human production of a particular pattern would be "impossible".
