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.
if an instance has ignored a community to the point it has become a toxic cesspool then the instance is a complete loss.
I have blocked several instances for the same reason.
