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.
The resources used to implement this aren’t the same as the ones that would be used to address some of the other issues, as the ones I know of are more social/legal ones.
I bet this was mostly done by a single coder who showed it off and management thought it was a fun thing so added it to the main site.
