I've forgotten which exact chapter and verse of the bible says one should shoot someone for stepping onto your property.

Perhaps something about how if you spell every word on a sign correctly it's an affront to God... it would be taunting Him with pretensions to perfection.

"You spelled "partyer" wrong, it's P-A-R-T-I-E-R."

I had friends that owned 100 acres in WI. There were 'No Trespassing" signs posted at regular intervals. That didn't stop anyone. They would stomp through with their dogs and kids and build little cooking fires, leaving garbage. In the off-tourist season, here come the hunters, stealing tree stands. After a couple years of this, he added a much sterner sign, and asked for help from the local DNR. Self absorbed jackass count is way, way down.

A guy posted signs that worked, keeping people out.

"Come on in! Let's talk Amway!"

to keep others from approaching.

None of the words are misspelled.

that's what the sign needs. Where is this place, now?

At least that is where he is vacationing.
