It looks like spammers are taking advantage of Gemini Notebook, public NotebookLM, pages to spam Google with all sorts of content. This includes pages on sex toys, porn, peptides, coupon codes and more.
It looks like Google is up to indexing over 12,000 of these pages. Google can easily wipe them from its index but it has not yet.
This was spotted by Gagan Ghotra and reshared by Glenn Gabe yesterday and it seems to be just getting worse. Gagan Ghotra wrote on X, "black hat SEOs are leveraging public NotebookLMs being indexable by Google as a new parasite SEO tactic!" Glenn added, "I think these will disappear soonish... But yes, of course public Gemini Notebooks are being spammed! From peptides to discount codes to porn to apps." It was actually first spotted by Charles Floate who posted on X, "I just HACKED the AI Overview using Google itself."
Here is what I see this morning:

And if you're wondering how this looks in the SERPs, here you go. BTW, you can view the prompt that created the notebook... Always interesting to read those. LOL https://t.co/G6jrzybGw0 pic.twitter.com/Z7b1ipcQK2

This won't last long but it is sad to see how this happens often when Google launches these products. Google should have a process for this for new launches by now.
Forum discussion at X.
Update: The next day Google removed all of these pages from its index:
OK, Google finally nuked the shared notebook directory from the SERPs (which contained a ton of spam). They could have done this much sooner, but hey, better late than never. :) https://t.co/uDXsGdAAT1 pic.twitter.com/C1bKO43mVC
