Maybe it's simple embellishment, but maybe in some cases it'll be a non-native speaker using an LLM as a personal translator as a way to participate and fit into previously-inaccessible communities. Either way, even with current tools it won't be hard to evade detection; In your example they simply used an inadequate prompt or model.

Definitely in two years it'll be a breeze just to give an LLM instruction on how "you" would chat and set it loose on a chat server without most people noticing.

Discord messages are usually pretty short so it wouldn't need a super-long context either.
