I can't speak for you specifically, it's just a trend I'm seeing and unfortunately your 2 day old account falls into that bucket. There's a lot of people who have a lot to lose or who are very afraid of what LLMs will do. There's plenty of incentive to do this.

I would be curious to see if I'm just imaging this or it really is a trend.

At the same time you have astro-turfing from LLM producers though, so...
