The title was shortened to fit the limit. Rental was the way to get the same meaning. You don't expect them to fit the entire situation in the title, do you? That ain't clickbait, that's just brevity. Hahaha! :)
It's definitely deliberate clickbait. It was written to imply that it's still a rental. A non-clickbait title could have been "One man's artistic wonderland, created in secret, given protected status."
Hahahaha! :) Sure, I get some vagaries of English can be hard to grasp, but you need to remember: I wrote it, I know what it was written to imply, it was definitely not written to be clickbait, you don't know what it was written to imply, and it doesn't imply what you say. Hahahahaha! :)
The meaning of One man's artistic wonderland, created in rental, gets protected status is that it was created in a rental, not that it still is. Hahahaha! :)
Would you prefer the other one? One man's artistic wonderland gets protected status in rental
BTW how does it matter to you if it's a rental or not? I think you must have rentals on your mind, right? Hahaha! :)
