@JulianOliver I have seen people accused of using LLMs because they write in all-lowercase. The accuser claimed that this was an attempt to avoid detection for using an LLM by promoting it to write in an unusual style. To someone who’s sufficiently paranoid even writing unlike an LLM is proof of LLM use.
I’ve been accused of using LLMs due to saying that someone was partially correct before disagreeing with the rest of what they said, as well as for using five-syllable words.
