Ask HN: Why have people started including GPT in their usernames?

I noticed here, and on other sites there's a number of new accounts that end in GPT: Jaguar_GPT, shat_gpt, ChumpGPT, etc. I don't really get the appeal of adding GPT suffix, especially when people act against GPT generated submissions. Is there any "reason" to this? Is this a thing?
