tl;dr: Here’s a small addition to how you can also scramble images so that “AI” scrapers will end up with a poisoned data set Earlier this year, I’ve written about how I setup this static website to not only serve human-readable data, but also “poisoned data” to mess with the scrapers that are used to collect the training data sets for generative “AI”. As static website deployments via Codeberg Pages et al. aren’t offering a

As this blog post is being published, we are sending out emails to all openSNP users with some news: OpenSNP will be turned off – and with that also delete all the data stored on it – on April 30, 2025 .

Some days ago, I saw the nifty little “comment” integration that FOSS Academic Robert W. Gehl has on his blog, which in turn were inspired by some other integrations.

tl;dr: Here’s a how-to for adding some “AI”-poison to your static site that’s hosted on Codeberg Pages (or GitHub Pages ). I’d appreciate some feedback on if this is useful/how it could be improved. If you’re running any type of website in 2025, you’ll likely be suffering from the impact of generative “AI”. Be that “AI”-generated spam posted to your site, crawlers bringing your server(s) down or just having
