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.
Then why are there several users who are anti-AI and not banned?
Inconsistent enforcement. The mods consider it within their rights to remove content purely on the basis that it's critical of AI. Giving some of it a pass (for now) doesn't change that.
