The thread on the Michigan coach phone call said “New Troll cornfielded. Thank you for your patience.”
What is cornfielded? Does it mean the thread is closed? These “in” terms sometimes befuddle me. It may be common to you more urbane posters, but I’m not one of them 
Help.
Does is mean the thread is closed?
Thread is open or at least should be.
I removed the troll’s posts and the replies to the troll.
I verified, the thread is open. I had it closed for 6 minutes to extract the troll.
Cornfielding is an old reference to moving the posts from the public part of the forum to a hidden area. It references a famous Twilight Zone episode; It's a Good Life (The Twilight Zone) - Wikipedia
It’s a reference to The Twilight Zone episode ‘It’s A Good Life’ (Season 3, Episode 8, 1961). A young boy has godlike powers. He changes small animals into hideous monsters, then wishes them in to the cornfield when he’s done playing with them. People get cornfielded too.

The term is a reference to an episode of the original Twilight Zone which was an adaptation of a short story.
A young boy becomes a tyrant who had mental powers. He takes people who anger him and transports them to be buried in a cornfield. It’s slang for make something disappear.
It is very dated now, but this Glossary of Terms is a good resource, especially for older threads.
Thanks, I have, in fact, done what you explained is cornfielding, I just never knew the term. I was partner and chief admin for a moderate sized forum and had to do a lot of cornfielding.
Thanks for getting that poster tossed. I knew on reading his first post that he was trouble. You probably did, too, but had to give he some rope.
Thanks for you efforts. Yours is generally a thankless job.

Actually, 2 posters flagged his trolling. Otherwise it might of been quite a while before I or another Mod found him as he was only posting in a single thread.
Reporting Trolls is very helpful.
I just had a horrible thought. Thinking of the ‘identify this sci-fi book’ thread, there was a recent discussion about a mysterious hole that people started throwing trash into. In huge volumes. One day, the trash started coming back. What if one day we login to find the journey to the cornfield was round trip?
Ya know? I didn’t think of reporting him or her.
I’ll have to be more away in the future.
Was it down at the quarry?
i think more than a few non-muricans / non-native-english-speakers struggle with those in-phrases …
cornfielding?
dogwhistling?
gaslighting?
etc …
Cornfielding is a sci-fi reference and specific to internet forums, so could be a little obscure.
But gaslighting? It gained popularity post #MeToo. And dogwhistling isn’t some exotic concept either. They’re hardly in-group phrases, they’re part of the general lexicon.
I think the past tense of cornfield should be cornfeld, not cornfielded.
Maybe cornholed? 
Then if you used a highlighter in the past to highlight a passage, was the passage highlit?
Speaking of cornfielding, I got an email notification that I’d been mentioned in a thread. I clicked on the link, and… the thread had been sent to the cornfield.
Where I grew up, ‘cornhole’ had the meaning you imply. Up here, ‘cornhole’ a game we called ‘bean bag toss’ in SoCal.
I would enthusiastically vote in favor of both changes.
I lived in the Midwest for 20 years. I’m well aware of “bean bag toss” by that name. But was roundly mystified the first time I heard it by that name. Probably much as you were.
Unrelated to the above:
Last night there were two rapidly developing threads, one self-immolation in the Pit and here in ATMB a whine by the same OP about their subsequent treatment in the Pit thread. Both of which are cornholed this morning.
Which is a shame because that Pit thread included my absolute nastiest shotgun blast to the face of my 20 years here. And now I can’t even refer back to it to admire my handiwork. Someone in cornhole-land can probably enjoy it.
While I’m aware of the term out here in MN, it still makes me blink when I hear it on the news, said with a straight face. It also gives me pause to see it listed on ESPN as “American Cornhole Championship Tournament”. My sniggering 15-year-old self just can’t help it.
My favorite mention of the sport of Cornholing on the 'Dope:
