Personally, more than 1 teaser is clickbait and I'd sooner see 0. That's true for me w.r.t. all content, automobiles, cellphones, laptops, speakers, audio components. That's personal preference and an opinion and others would choose differently which is understandable and respected.
From a prompt engineering point of view, that answer you received could be foretold both regarding ratio and societal norms.
(I input the same initial prompt into ChatGPT latest version and received the same baseline response and quite a bit more verbiage all reinforcing the answer).
In the same session, try this prompt:
"Please confirm whether your answer is based upon existing norms and patterns in the Social Media community."
And then this:
"Now, please analyze the comments on teaser posts that those samples are drawn from and let me know what their consumers think of the teasers. Are there complaints regarding use of teasers?
Should I consider content consumer feedback?"
