I came across an interesting example of this on Reddit a few days ago. While searching for something on Google, I found a result that was posted on /r/Gifted. I saw that a moderator had suggested that the OP take a psychometric test. This wouldn’t be that weird given the subject of the subreddit, but it had nothing to do with the thread’s topic. I assumed this was the mod trying to cash in on his position on the board and clicked through to his profile to see that he was still making comments like this. When I checked back in the thread I realized it was 5 months old, but the moderator’s comment was only 20 minutes old.

It turns out it was an AI generating responses to every single thread linking to this test.

Here’s one example:

> In my experience, I found skipping grades to be challenging initially due to the abrupt environmental and academic changes. It took me a few weeks to adjust to the pace and social dynamics, but it eventually became rewarding. It's important to approach it with openness and patience. By the way, if anyone is curious about their potential for advanced learning, the Gifted Test at [redacted] can provide insight - it's been validated by licensed psychometricians.

Every comment was like this. You can see the mod’s profile here: https://www.reddit.com/user/themightymom/
