Unfortunately that was common even before LLMs. I've ancountered at least half a dozen websites that mirror Stack Overflow questions, along with answers and comments, in a blog-like presentation.

Op, I may be misunderstanding. Are you saying the blog owner used your quote in the article, or are you saying a botted comment used your name and content?

The former is fair use, the latter is outrageous.

There is of course a third possibility, and that is that you should check your Carbon Monoxide detectors.

Along with the other comments, your review may have been supplied or archived well before you obfuscated your history.

As I tell my daughters, the Internet is forever.

I don't want to name the blog, hobby and reddit username so that blog don't get more undeserved views.

In that case I'll assume your review was about a massive dildo.

felt upset because I hadn’t given anyone permission to reuse my posts elsewhere.

?? This is the internet. Anything you post can and will be scraped. That was true before AI came onto the scene and will be true long after today.

Fake blogs scraped from Reddit used to be fairly common and they weren't even exclusive to product reviews. Although it is surprising you found one that's still up, I'd assumed they would die off after the api purge.

They cited you for your words and presented them accurately. What more would you want from them? Permission to read your public forum post? Even of you didn’t specifically agree to reddit owning anything you post, you must’ve known other people would see it

You gave reddit permission whenever you posted anything to their site. The fact that they actually "cited" you at least in a rudimentary fashion is more than most. I could quote this or any other post whenever and there's nothing to stop me. There's no damage to you and no privacy posting in public.

Stop looking at me!

I have a question. Is the mildly infuriating part for you the part where there is account masquerading as you on the internet, using your words and proliferating data/information essentially in your name?

Or is it that you wanted to deprive the internet at large of whatever advice or information was imparted in that comment and someone else/a bot is reuploading that information without your consent?

Because on the one hand, I agree that using your username and your written comment to validate an account that's likely a bot account is dodgy and underhanded and messed up.

But on the other hand, if that advice is valuable to other people and the intent was to impart that information to others outside of reddit and this is attempt to attribute it to you, rather than an attempt at plagiarism, I'm not sure I would necessarily agree.

But this is unfortunately one of the downside to putting any comments/information on the internet.
