This free font can trick AI scrapers into swallowing gibberish instead of your content (www.techspot.com)

Most mass scrapers, on the other hand, simply grab the raw HTML underneath. ShieldFont exploits this difference through an automated process called OpenType glyph substitution.

That said, because the whole defense rests on scrapers reading code rather than screens, taking a screenshot of a shielded page and running OCR on the image can still recover the real words.

Screen readers used by blind readers also work from the code, so they read the decoys aloud. ShieldFont ships with a beta feature that provides those readers with the real text instead.

Unfortunately, most people don’t care

There are laws about accessibility, at least for public websites, and probably for larger websites as they have such a large audience that disability can't be ignored (as much).

In my experience, those laws aren't followed much in reality. The biggest sites, sure, but most smaller sites are a mess under the hood. As long as something is "technically usable", even if very awkward and annoying, it's often hard to sue or anything like that. Maybe it's different in other countries though, I live in Australia.

Next time you use a website, try only using your keyboard to navigate it and accomplish your task, and you'll see what I mean. It's a rough test of how much they value accessibility. For example, many websites disable the border around what you're highlighting, so you have no idea what the tab button is about to click. Or popup windows don't actually change your tab selection, so you have to tab through literally the entire page in the background to get to the popup window. Stuff like that; technically usable but annoying as hell.
