and therefore they will not stop using AI (I noticed many accounts posting In the gambling section in a completely suspicious way, but it is not easy to prove manipulation)
Those users want to show if they have an interest to gambling, since we all know most campaigns right now are promoting gambling, when they already earn sufficient activity and merit, they will apply the campaign and raise the chance to get accepted. They don't want the managers or other users to judge if they shift or change their posting habit just to fill campaign requirements.
If it's not then it's the same as plagiarism to me.
Will you ban every users who post using AI? I see @OP didn't get banned yet.
