To me, AI shouldn't underestimate anyway. AI captured a large market in the online world. But it needs to be used properly. For example, you may create codes through AI. You may try to create some good codes, like creating a marketplace or something like this. On the other hand, you may also create hacking codes that could help hack somehow, or you may create scamming sites through AI codes. It means it depends on your intention of using AI, either it should be discouraged or encouraged.  If your forum posts fully depend on AI, then it should be discouraged, but if you use it to fix grammar, then it shouldn't be discouraged anyway.
