This website contains age-restricted materials including nudity and explicit depictions of sexual activity.
By entering, you affirm that you are at least 18 years of age or the age of majority in the jurisdiction you are accessing the website from and you consent to viewing sexually explicit content.
A trained Gen. AI model does not just view it though. It generates content out of it which is copying and prohibited by plenty of licenses (GPL-licensed open source projects for example).
I think the copy they’re referring to is the initial one that puts it on the Internet without a paywall. Not those that come along after and take a copy.
