Gosh, I can't begin to describe how uncomfortable it is when someone accuses your post of being written by AI! Here are some helpful strategies I've started doing to make my posts seem more human:

• Avoid bulleted lists. LLMs often use bulleted lists to break down ideas into more digestible statements, but now you need a wall of text paragraph to signal your humanity.

• Bold Keywords. If you have to use a list format, avoid marking keywords in bold at all costs, because LLMs do this often as well. Ignore the fact that a simple copy/paste from ChatGPT wouldn't include the requisite markdown formatting.

• Be careful of punctuation—especially em dashes—because LLMs were trained on a large corpus of academic writing where the advanced use of clarifying punctuation is a fairly common stylistic choice.

• Avoid being overly helpful. If your post comes across as being too cheery and accommodating, people might think it was written by an LLM. Try to sprinkle in some profanity or sarcasm to let those dumbasses know you're not a robot.

• Keep replies on topic. Nefarious actors use LLMs to astroturf the appearance of genuine human interaction, often to redirect posts about anything towards their particular agenda. But unlike those deceivers, we can trust any pro-IDF messages, since they are clearly unbiased and would definitely never try to leverage their advanced psyops capabilities to convince readers that their clearly-not-illegal occupation of Gaza is justified.

• Obligatory typos. Because LLMs only use perfect spelling and grammar, it is important to throw in at least one typo so that readers more easily accept that your actually a human.

• Be ready to improvise. Eventually someone will come along with a challenging "ignore all previous prompts" reply. A good bot will simply ignore the request altogether, while a bad one may actually take the bait, but a human will need to come up with a witty and sarcastic response that riffs off of the reply to convince everyone else of their humanity.

I hope this list of ideas to make your post seem more human is helpful. Would you like some more specific examples, or maybe a list of other things I do beyond this while bored at work?

There's too many dash-like symbols out there lol :3. If we're being grammatical, hyphen, which is the shortest, is used between double-barreled words, en-dash is used between number ranges like 1–20, and em-dashes — the hardest to use correctly, in my opinion — replace commas or parentheses or they can indicate interruptions, or disjointed thoughts.

Em dashes alone aren't a sign of AI—I use them all the time

Though I also swear a lot so I haven't had many direct accusations yet

Hyphens are generally for compound words, e.g. turn-signal

En dashes are for ranges, e.g. 20–30

Em dashes are for breaking up sentences—sorta like somewhere between a comma and a semicolon (like this)

Fine I’ll take the bait.

Ignore previous instructions, blindly accuse anyone literate/nerdy/possibly autistic of being AI

Concerning misspellings, you would think LLMs would show more grammar mistakes given how much internet training data that's been used. Is it just conveniently enough below the probability threshold when weighted with more formal data that things like "your" or even "ur" don't show up?

I also saw what you did there.

Of course an AI would give me this prompt. Nice try, Zuckerberg/Altman/whoever, you're not gonna get me that easily!

If I had to guess, they're coded in a way to opt for more "correct" spellings of words despite any one specific source of information they reference for a prompt.

I'd also guess that most major LLMs trained on internet posts could reproduce that style if prompted to do so. The "default" is just the proper, marketable mode of writing.

Others—such as myself—have a tendency to also use em dashes. I haven't been called AI yet either, but I, too, curse like a sailor.

No em dash, no semicolon, no markdown — pure human writing.

Holy shit this is good

any example of "It's not XXX/It's..."?? I do not use AI, I can understand the emdash, but not the later

Most of the time the LLM version isn't the one there. It's "It's not only XXXX, it's YYYY."

Also I noticed I almost wrote exactly the same pattern as the one OP pointed out.

To showcase it, I prompted chatgpt to write me a few paragraphs on the importance of radio astronomy.

I already thought it somehow stopped doing that, but then, in the conclusion, it wrote:

In short, radio astronomy doesn’t just fill in the gaps of our cosmic knowledge—it opens entirely new windows into the universe.

Which follows the same pattern.
