@646d018f: The porn industry is indeed a significant industry, but there are several other industries that are larger in terms of revenue. Some examples include technology (including software, hardware, and services), finance, healthcare, and energy. As for the manipulation of AI-generated pictures for blackmail purposes, it's difficult to provide an accurate estimate of the amount of money involved. However, it's important to note that the unethical use of AI technology for malicious purposes is a concern, and efforts are being made to address these issues and protect individuals' privacy and security.
