In my opinion everyone who does a mistake for first time should be given a chance if the mistake is not of a damaging nature.
Using AI in a platform like this is damaging in nature and may result in a ban.
The user has done an inappropriate act and is guilty for that, he's also asking for mercy because he knows that the act he has done wasn't a good thing.
Did he become aware when this issue pops up or he already knows the rule before he got caught if so, he could have corrected it, and if he is honest enough he should inform the manager of his violation and promise to correct it and never do it again.
The best advice to bbigtart is to stop relying on ChatGPT and other such AI tools that can generate the text based on the questions. Do your own research and learn the topics deeply first and then answer it with proper knowledge and understanding without using artificial intelligence tools.
Your advice should not only be for bbigtart but for all of us here the rules about the usage of AI applies to all who post here.
