LLM generation in general provides the most use to scammers and the like. Generate emails which people won't read, generate articles which are just honeypots or rip-offs, generate images to said articles, generate more and more spam.

Every legit use case for LLM practically requires that human would verify the result manually, at least briefly. But spammers can enjoy skipping that step, since content was never a main priority in the first place.
