"Spoiler Free Map" sounds like GM speak for "full of obvious misinformation" just like "friendly seeming quest giver" means "Mr Johnson wants you dead"

The spoiler free map lacks whore island. Archer is disappoint.

Tell a story about obvious misinformation that the players didn't realize was a lie.

The serial killer wore a shirt that said, "NICE LADY".

Everyone trusted her impliciy.

With this being a Raxon story, I was half expecting you to finish "Everyone trusted him implicitly."

Once upon a time, the party was told that a whale was approaching. But it wasn't a whale, it was drow pirates. They have shot at every aquatic mammal since.

I make spoiler-free maps too! And since I use Adventure Path modules, it takes a while...

I hear that.
I was lazy once, once, and simply gave them the stock map. It had a secret passage shown on it. They decided to go looking for it. They, of course, found it, and delved right in through this super secret passageway. Thinking to themselves oh yeah, this is going to be so easy, we'll take them by surprise!
They immediately ran into a monster whose CR was like 4 higher than their level and were summarily eaten.
