Are you ok? You've doubled down on nonsense. Seriously, take a breath. Look into some treatment for anxiety.

The whole danger is that AI text generation doesn't misspell, and comes across highly confidently.

There's actual research out there on spotting AI generated text. Most of it is based off tone, frequency of some specific phrases, and sentence structure.

If you're mixing this with the idea that spam emails and scamming comments are often misspelled, that's done in an attempt to avoid word filters, and also to help ensure that people who fall for them are dumb enough not to notice, making them easy marks more likely to overlook other warning signs. If they aren't trying to get you to take an action, or a coordinated push to manufacture consent, the chance of AI is low.

Also, the statistics about internet traffic you're thinking about is about bots. That's largely scripts and web scrapers, less so automated posters making arguments multiple levels down incredibly quiet threads on low user count social media like lemmy.
