Wish it was just bait, but I was on the receiving end of similar messages from someone about 10 years ago. They would comment on my art page complimenting my art, and I always replied saying "thanks", and we never interacted beyond that. We definitely never met IRL. One day I woke up to hundreds of DMs from him that sounded dellirious, that they would like to be my partner and that he had "deeply analyzed my art and he knows me for real". Very unsettling and creepy stuff, spiraling into self-hate. There are some real troubled people out there, and now they have access to AI's allucinations to feed their own, sadly.
