I'm tired, and I don’t want to do free accessibility consulting for this website owner, so I'll outline only one way this won’t work for screen reader users out of many.
Aside from the fact an LLM made the website, and the font as well, the reason it doesn’t work for screen reader users because, even on that demo page, a timer has to be activated. A button must be pushed. A timer activates, and a screen reader user must find the fixed bit of text again. The website makes it sound as if it should be just automatically accessible/visible to the screen reader, and that fails.
Aside from the screen reader issues, that's not the only one, but I don’t want to do free accessibility consulting for this website, some of the other issues include but are not limited to…
It doesn’t prevent scraping.
It doesn’t prevent taking a snapshot and then doing OCR on that screenshot.
It breaks custom fonts anybody has disabled or enabled.
It breaks copy and paste.
It breaks for people without JavaScript enabled.
It breaks for anybody using a good ad blocker.
It prevents search from working on the website.
And many, many, more things that are in my replies.
If you want to learn about me and my screen reader, my FAQ page is below the website I'm talking about.
If you use this font to protect your text from AI, it also blocks *me, a human* because I use a screen reader. I did try the demo. If you want me to remove your RSS feed, this is the best font to prevent blind people from reading your blog/words. That timer is an inaccessible solution and that isn't it's only screen reader failure. https://shieldfont.org/#hero
