There are "humanizer" scripts that these people like to use. This one is not the typical style I see in my online moderator adventures, which is usually "lowercase everything and remove all punctuation except periods", as if we are repelled by em-dash use and not the tortured prose.

I like the removal of a random definite article, to simulate an ESL writer and garner sympathy for using LLMs as a "tool to clean up posts". Heavens, they would never even think of using their Claude subscription to be a slop factory, that would cross a line.
