I have a query for @Ultegra134, @nutildah, @lovesmayfamilis, @Dark.Look, + any other member who deals with AI detection.
I checked the post history of one account (can't disclose, don't want to make the AI spammers smarter + I can't prove anything right now). Out of his last 50 posts, 32 are showing 100%  detection by Sapling AI. No other detector like Copyleaks and GPTzero is showing AI. Posts are long and detailed (IMO, AI). What do you make of it? 
IMO, this is a case of humanizing AI content. I mean, is it normal to have such a high amount of false positives by Sapling AI? Have you encountered this before?
I can pm the details to @Ultegra134, @nutildah, @lovesmayfamilis with the condition of confidentiality. 
I am not accusing anyone right now. It is a part of my brainstorming to detect AI spammers who are using humanizers.
