I don't think he cares or he noticed that he was reported for AI usage. As long as he remains unbanned, he'll continue spamming the forum, the thread he posted to is also filled up with AI replies, possibly from the same person, but different account.

From my understanding, if the reported user only has a couple of posts, the majority of which are AI, he'll be banned, although a user with a larger number of posts, such as this one, despite them being spam on bounty campaigns, he'll remain unbanned and in the worst case scenario, have the reported posts deleted.
