Summary:
I downvoted pro-AI comments in a post in leftymemes community. It was LLM generated polandball comic (Which is objectively pathetic as fuck) that showed up on my feed, blocked couple of users who I thought were unhinged, and have blocked the whole instance on my client after realizing how rabid these morons are.
I didn't go looking for AI posts like a vigilante.
One user in question got miffed for being downvoted and banned me from places they moderate.
There is no actual rule against criticism of AI. It's an ethereal rule that they use to exert authoritarian behavior.
