What degrades conversation is to lie about something being not AI when it actually is. People pointing out the fraud are right to do so.
One thing I've learned is that comment sections are a vital defense on AI content spreading, because while you might fool some people, it's hard to fool all the people. There have been times I've been fooled by AI only to see in the comments the consensus that it is AI. So now it's my standard practice to check comments to see what others are saying.
If mods put a rule into place that muzzles this community when it comes to alerting others a fraud is being affected, that just makes this place a target for AI scams.
