I am someone who believes in adapting to technology as it advances. I do not see the use of AI in the forum as something that should be forbidden or considered too sacred. I have even shared my thoughts before about the use of AI in the forum in my post
Using AI to Our Advantage in the Forum.. However, if we are going to encourage the use of AI in the forum, we should also be careful not to breed tons of lazy posters with zero originality.
I share same thoughts as you and if AI contents should be allowed in the forum, it should be AI for an AI and not mixed with human's knowledge. What i mean is that if a thread is created by an AI and the OP provides the source of the AI generated contents, those who will make replies on those threads will also have to get their texts from the AI. I think if it is done that way, it can be considered but yet should not be excessive.
AI for AI? This sounds like a giving permission to users to misbehave.
