I received a few
comments about my game and immediately suspected them of being A.I.
One of them mentioned something in the game that wasn't described in the description, so I could mark that one as real.
The other two were generic comments that could be said about many games.
I looked up their user histories and saw that those people did make comments on other games that did include specifics that could only be obtained by playing the game. Some of them were actually negative. They were were all spaced apart by minutes, which is about the right amount of time for someone running through the games in a jam.
So, these were legit comments by people that probably did try the game for a minute. Their only crime was not having a unique writing style or especially deep commentary insights. They shouldn't have to. I personally want to be able to say things like "this is fine" or to be bland without being suspected of non-humanity.
Automated commenting was always possible before LLMs, but there was a technical barrier to entry that made it the domain of commercially-driven spammers and state actors like Russia and Palantir.
