Legally just leaking nudes is dissemination of intimate images. Misdemeanor or summary in most states. Revenge porn is a felony (in most states) and includes leaking with specific intent to cause harm to someone
so like leaking onlyfans vs leaking private pictures vs leaking something only to someones job
The problem is that it varies so much state-by-state and country-by-country that you can't easily put one description on it. In some states, the way the law is worded, it would be a crime to disseminate leaked OnlyFans content. This is part of the reason these laws have been so controversial.
Any nudes shared without consent is revenge porn
