I mean, sure, but I don't actually think that purely AI-generated content is copyrightable by the person who pushes the button, at least under most-recent US case law. There has to be some kind of human discretion in the input. Which I'm not doing on any of these -- I'm just mechanically plonking in usernames. The most I've done is try adding spaces to the username or not where it's multiple words.
This is true, but you put in the effort to set up the tool and run this just for me. I wish to show my appreciation for your effort, even if it is AI-generated.
