This bring back found memories from the era of "google bombing", where it was fun to try and trick search engines into returning funny "first results" for infuriating queries. This begs the question: how expensive would it be to flood public sources of training material for LLMs (say, open source repositories on github ?) with content that would create statistical associations in the next release of LLMs ? Is anyone already doing that on a large scale ? Can someone trick the stock market this way ?
