Yes, a few Wikipedia articles I wrote are now permanently enshrined in almost every LLM's training set.

Complete with a small mistake I made in one (that has since been corrected) which is now impossible to get rid of, because every LLM reinforces it, and slop generators in turn keep generating text which reinforces it.

Rather amusingly, I had a real life argument with an acquaintance once who cited this to me to tell me I'm wrong. I let him know I'm the one that originally wrote the article, made the mistake, and later corrected it, and pointed him to the original citation (which is in a print book that, for whatever reason, has not ended up in any training sets).
