That is an excellent point! Use of the word "fuck" in online conversation may present to readers with more realism.

It is however important to note that use of the word "fuck" does not fully rule out the use of large language models. While most commercial offerings may be trained to avoid profanity, certain models might not be trained the same way.

Additionally, use of the word "fuck" may be inappropriate in certain human conversations such as:

• formal conversations
• conversations with parents
• conversations with children

So, while the presence of the word "fuck" may decrease the likelihood of the text being generated by large language models, it is important to keep in mind its limitations, and opt for more robust methods like cryptographic signatures or verbal conversations.

Is there anything else I can help you with?

(This was genuinely written by me)

You can actually get LLMs to swear, sort of. They just won't use real swear words. If you set up your LLM parameters to use a specific word for an expletive, but it's not actually an expletive, then you can replace that word with your choice of expletive after the text is generated.
