this happened months ago. i cannot keep it in any longer. a while ago i went on a porn site ive never been to and it asked if i was over 18 and i misclicked and said no and it automatically sent me to google images of puppies and kittens. i still cannot get over how funny this is.
If I remember correctly this used to be a standard sort of thing to do on the entry page, back in the “fanfic authors post our stuff on our own personal Geocities sites” day.
(I mean, not always puppies and kittens… but it was pretty common for the “no I’m not old enough” link to go someplace chosen for being comically, exaggeratedly kid-friendly.
And yeah, I always got the sense it was intended at least partly as a joke for the benefit of the intended adult audience.)
