Lubach (Dutch talkshow comedian) has done a piece on how it turns out that, in terms of websites written in Dutch, there is an unseen iceberg under the water: a forum dedicated to horses that has, over 25 years, amassed over a hundred million posts from very dedicated and loyal users, making it... one of the main sources of Dutch language training data in LLMs.

This has caused it to be massively upranked in google search results as a Ground Truth, and pretty much every subject has been brought up at least once in those hundred million posts about horses, so... the Dutch internet is just horse-themed now. 🐴
